None of the links you provided us with actually lead to runnable code. Even the .exe does not run because of missing graphic resources. If you want us to help with your actual code you will need to zip the .bas file and all needed resources to a folder and share a link to that. Put everything in a new folder Right Click on it and choose Send To then choose zipped folder. Now put the .zip somewhere we can share.

I did run the EXE (may be it was previous version) but alas my montor works only up to 1280x1024, so I cannot work with program written to 1900xsomething.

Or use LBB's capability of embedding the resource files in the EXE (they are compressed when you do that)!

Rod, I already posted my full code in previous post in this thread 
Nevertheless, I have zipped all the files again and here is the link the this file: http://home.citycable.ch/flotulopex/LBB/ZIPped/
Thanks a lot for the already provided solutions. Unfortunately, I can't use "graphics" type window as I can't get rid of the title bar (or did I miss something?).
The resolution of 1920x1080 is due to the fact that this program is displaying via a beamer on a quite big screen (3m x 1m70). I already tested with lower resolution but the images look crap

Yes, you evidently missed my reply in which I stated that you can either use STYLEBITS to remove the title bar or alternatively use a WINDOW_POPUP containing a GRAPHICBOX control. There's not much to choose between these solutions.
I know that Conforums doesn't always reliably list all replies in the "10 most recent posts on this forum" summary, but if you go directly to the thread you should find them.

Ideally your program should adapt to the current DisplayWidth and DisplayHeight values, that way anybody will be able to run it. Even if the text and image quality is poor on smaller screen sizes, that way you are more likely to receive offers of help.

Ok, your code is still not showing me what's wrong because of the screen size. Can you put together a very simple demo of what the problem is using a small 800x600 screen. You don't need a bunch of code just enough to show us what it is about the statictexts and bmps and text rendering that isn't working for you.
Even try adapting my demo to show your problem.

Hi Rod,
Thanks for helping
Here's the link to a minimized piece of code in a (for you) 800x600 pixels resolution of what I want to achieve.
http://home.citycable.ch/flotulopex/LBB/800x600.zip
For any reason I don't understand right now, it's working (!!!) meaning: I can now overlay a statictext over a bmp backround. I started to search my original code why it is not working there.
If you still want to test it, run it and left-click anywhere on the left side of your screen will make some text appear while left-clicking on the right will make it disappear.

I'm not enthusiastic about doing that. It is reliant on the window Z-order and on the correct use of the WS_CLIPCHILDREN stylebit, and whilst this should work it seems to be taking an unnecessary risk.
The LB 4 Help file specifically states "Some controls do not work properly when placed in graphicboxes or graphics windows. If there is a need for text display within a graphicbox or graphics window, use the graphics text capabilities rather than a statictext control". Although LBB makes no such stipulation, there is a danger that you may break compatibility with LB 4.
Also, in order to make the edge of the STATICTEXT control invisible you must precisely match its background color to the BMP 'behind', and whilst you can do this in LBB (because the BackgroundColor$ variable can take an RGB parameter) in LB 4 you can't.
Obviously I don't think retaining LB 4 compatibility is that important, but neither do I encourage unnecessarily breaking it.
Richard.

The simple version just posted a few minutes ago works well because it is ultra-simple...but I can't use it.
I'm now trying to display both texts in different colors and trouble begins.
Let's try to solve problems one-by-one. Here is another piece of code, still 800x600 pixels where I display now 2 texts.
http://home.citycable.ch/flotulopex/LBB/800x600_colors.bas
How do I do this?

I will not be able to use a graphics type window anyway since I can't get rid of the title bar

Please stop saying that! I have twice told you how to remove the title bar; the second time you even thanked me for the information. I have even given you two different methods, which work in both LB 4 and LBB (example program below).
Richard.
Code: UpperLeftX = 100 : UpperLeftY = 100
stylebits #w1, _WS_POPUP, _WS_CAPTION + _WS_THICKFRAME, 0, 0
open "" for graphics_nsb as #w1
#w1 "down; fill blue; backcolor blue; color yellow"
#w1 "place 80 140"
#w1 "\Graphics with no title bar"
#w1 "place 120 160"
#w1 "\(method one)"
UpperLeftX = 500 : UpperLeftY = 100
graphicbox #w2.gb, 0, 0, WindowWidth, WindowHeight
open "" for window_popup as #w2
#w2.gb "down; fill blue; backcolor blue; color yellow"
#w2.gb "place 80 140"
#w2.gb "\Graphics with no title bar"
#w2.gb "place 120 160"
#w2.gb "\(method two)"

You're right. I thanked you for helping and so I went searching again about the stylebits for hours but couldn't find any working solution. Even if I would have found the correct stylebits, I probably wouldn't have been successful anyway since I wouldn't have had the idea to put it before the OPEN command.
I still don't understand the logic of the semantic in LB/LBB* - I need more time to get this.
Method 2 (window_popup type) is the one I already use in all the code I made up to now.
*I'm used to program microcontrollers. The code making is really straight forward.

From the LB 4.5.0 Help documentation: "The STYLEBITS command must be issued before the command to open the window".
You would have to ask Carl why he chose that approach, rather than the (perhaps) more natural one of making the style a parameter of the OPEN statement. My guess would be because it was an addition to the language, and using that method meant that the OPEN statement could be left unchanged.

One of the nice things about writing a clone of a language is not having to justify the way it works!

Only had time to look at the code today. As Richard says you should not be attempting to combine statictext and graphicboxes. It is perfectly possible to do everything you want inside the graphicbox. You can lay out the text precisely and you can have the mouse react to clicks on ir inside the text area. So forget statictext and practice some of the graphics commands.
Code: ' 800x600
NOMAINWIN
UpperLeftX = 0
UpperLeftY = 0
WindowWidth = 800
WindowHeight = 600
GRAPHICBOX #Main.GBx1,0,0,800,600
STYLEBITS #Main.GBx1,0,_WS_BORDER,0,0 'remove image's border
OPEN "800x600" FOR window_popup AS #Main
'get the handle of the graphicbox
hWD=hwnd(#Main.GBx1)
'get the handle of the DC
CallDll #user32, "GetDC", hWD as ulong, hDC as ulong
'set text to render with transparent background
calldll #gdi32, "SetBkMode",hDC as ulong,_TRANSPARENT as long, re as long
[MAIN]
#Main.GBx1 "font tahoma 100 bold"
#Main.GBx1 "down; fill darkred ; flush bak"
#Main.GBx1 "when leftButtonDown [MouseLeftButton]"
WAIT
[QUIT]
CLOSE #Main
END
[MouseLeftButton]
IF MouseX < 100 THEN #Main.GBx1 "discard ; redraw bak"
IF MouseX > 100 THEN
#Main.GBx1 "discard ; redraw bak"
#Main.GBx1 "color green ; place 100 300 ;\TEXT"
#Main.GBx1 "color red ; place 100 400 ;\TEXT"
end if
IF MouseX > 750 and MouseY < 50 then close #Main : end
WAIT
