InvalidateRect in windows Me?

[msdawy2]

Hello...
I am having a weird problem... I have written a program (MDI) in visual c++ 6, it runs great in win2000 and XP. But in win Me, i tried it today, and i got shocked!

InvalidateRect() does not work correctly. When i click on something, it should get selected, I invalidate the rectangle around it, but in Me, it doesn't work! I have to minimize and maximize, or click several times for it to understand the InvalidateRect..

Why does it do this?
Any help would be greatly appreciated...
Thank you very much in advance....

Try after InvalidateRect to call UpdateWindow. InvalidateRect invalidates a portion, but draws nothing. So, drawing is fired when window receives WM_PAINT, a message with very low priority.

But, i tried it and... nothing changed! the behavior remained the same...
Is there any other way to FORCE a redraw now?

Thank you very much in advance..
