Is _WINDOWHANDLE working properly?

[TerryRitchie]

You've encountered an old issue with QB64 where a slight delay needs to be added after creating the screen so the _WINDOWHANDLE will return correctly.  I forget the exact reason, but just that adding a small _DELAY fixes it.

Add a _DELAY .25 right after scetting the SCREEN call and it should work.

EDIT: I tried using 'Do: Loop Until _ScreenExists' in the past, you may find it in some of my posted code, but I've found that it doesn't always do the trick, so I went back to adding a _delay .25 which never fails.

Yep, that took care of it. Thanks Dav

Perhaps a note in the Wiki under _WINDOWHANDLE about this bug and how to overcome it may be appropriate.
