Hello,
I have appearance problem in TabCtrl on one machine running Windows XP using Ultimate++ 3211. Problem appears after setting transparent (opaque) image to a tab using tab.GetItem(index).SetImage(...). Then after switching through the tabs it looks like this:

index.php?t=getfile&id=3259&private=0

index.php?t=getfile&id=3259&private=0

The mess in the last tab is certainly a distorted square from the first tab.
I can't reproduce the problem in a small test application but after some research I finally found something interesting. In file ImageWin32.cpp I've changed this one line in Image::Data::PaintImp method and it helped:

	if(GetKind() == IMAGE_OPAQUE && paintcount == 0 && sr == Rect(sz) && IsWinNT() && w.IsGui()) {
		LTIMING("Image Opaque direct set");
		SetSurface(w, x, y, sz.cx, sz.cy, buffer);
//		paintcount++;  /* removing this line helped */
		return;
	}

I still do not understand the issue completely but if you have any idea as how should I continue with the research I would appreciate it.

Thank you for your help and have a nice day Smile
