Hi,
When directly scrolling the selection on the DropList's fixed part using the mouse wheel (or with keyboard arrow keys), the current selection position jumps to wrong item when it crosses a separator which is not the first one in the list. It also allows selection of the separator, which it should not.
DropList droplist;
// ...
for(int i=0;i<10;i++){
droplist.Add(i,Format("%d",i));
if(((i+1)%3)==0) droplist.AddSeparator();
}
To see the problem, try to scroll from 0 to 9 and back.
// Tom

Yes, I tested with the fix.
The initial test case code applies for this one too: Although the wheel and arrow keys both now work on top of the fixed part of the control, the arrow keys can not move the blue list item selection bar on top of the dropped list part when the selection bar encounters a separator.
