Blitz3d Fullscreen ?

hi @all
Facts :
I create a dll that will open a Dialog in the Blitzwindow.
the user must select a box and then i kill the dialog with
Dialog end.
This works fine in windowed mode .
But if i use Fullscreen the dialog will not kill .
If i use the Alt-Tab key 's to switch between programm's
and come back to my Application the Dialog is killed
and the Programm works fine !!!!!!!!

what should i do ?
anyone know's a Win Api call to solved this problem ?
or what's wrong ?


Thx for help

Try to include this before destroying the dialog:

// hWnd is the dialog handle
ShowWindow(hWnd, SW_HIDE);
UpdateWindow(hWnd);
ReleaseDC(hWnd, GetDC( hWnd )); // not sure about this line

THX Marcelo !

This will solved the problem

ShowWindow(hWnd, SW_HIDE);
UpdateWindow(hWnd);
