I have a window with a WkHierarchicalListBox widget and lots of little icons shown in the tree view within this widget. This all is done under Windows XP with XP2 (now with ATI graphic card - which is a new one, before that I had a Matrox card).
My desktop settings are set in the way, that the window content IS shown, when I move or resize a window.
Now when I resize this window (from the lower right corner) very fast (making it smaller and larger again) for some times I get the following error:
- Code: Select all
