Hi,
I have a problem with the scrollbar in edit control.
In my case I use richedit, but it appears also in the "normal" editcontrol.
The problem ONLY appears, when working with my program (including editcontrol) and another program like notpad on the other screen.
It appears when using the scrollbar of notepad, then my scroll bar and so on ... (vertical scrollbars only)
and then suddenly the area behind my scrollbar gets highlighted (black) like selected, above and below,
if i move the mouse to the left during pressing, the whole area behind the scrollbar gets highlighted in
