IDA (yes, that again :), doesn't redraw its toolbar buttons properly. When you
move the mouse over them, its meant to have a button rollover. Under wine
however, it highlights the button, but does not de-highlight.
Some investigation shows that these toolbar windows have the TBSTYLE_FLAT
style.
Some more investigation (with spyxx) showed that under windows, each toolbar
receives a WM_PAINT message, and, when the mouse leaves a button (and it
should be de-highlighted), it receives a single WM_ERASEBKGND message.
I have concluded that the WM_ERASEBKGND is sent from within WM_PAINT when the
toolbar detects that the mouse has moved off a button and wants to
de-highlight it.
Lemme know what you think.. any suggestions greatly appreciated.
