The draw() procedure is:
"
procedure draw;
begin
if zgl_Resized then begin
zgl_Resized := false;
wnd_SetPos(mainfo.renderwindow.left,mainfo.renderwindow.top);
wnd_SetSize(mainfo.renderwindow.ClientWidth,mainfo.renderwindow.ClientHeight);
end;
pr2d_Rect( 0, 0, mainfo.clientwidth, mainfo.clientheight , $252537, 255 ,
PR2D_FILL );
text_Draw( fntMain, 0, 0, 'FPS: ' + u_IntToStr( zgl_Get( RENDER_FPS ) ) );
application.ProcessMessages;
...
"
application.processmessages() shows the popup menu in a nested main loop
because menu handling is modal. -> application.pocessmessages() does not
return until the menu has been closed.
I don't think one should call application.processmessages() from a OpenGL
render procedure.
