What knowledge do i lack really... I obviously have gone through the docs plenty of times for me to even comment on the two... Would be helpful if you identify my misconceptions regarding the two fuctions...

Code:

InvalidateRect(hdc, NULL, FALSE);

: Updates entire client area

Code:

InvalidateRgn(hdc, region, FALSE);

: Updates specified coordinates, region must have been created by CreateRectRgn() or similar functions...

Code:

InvalidateRect(hdc, &areaRect, FALSE);

: Updates specified coordinates (areaRect)

Now, where's my fault here?
