Thanks to both of you for looking into this.

@Skid:
This bug (as it is one for me) is NOT ONLY when resizing.

It also happens, when I select a gadgetitem.
The whole listbox, be it icons, text or both is pain white for a second.

If it were only a bug in windows. Other apps such as ms word or exel should have the problem as well. But there it looks fine.

This flickering is also visible in the max ide. Just resize it a bit. The Toolbar and Treebox to the right are flickering as well.

I would code the workaround you've mentioned myself, but I don't know C... :(

If you only update the areas of window that really have been modified it should also give you a performance increase on larger Lists, Toolbars and Treeboxes.

So such workaround could really improve bmx in many areas at the same time imho.
