Summary: Inital size of scroll bar "thumb" incorrect
           Product: Wine
           Version: 1.0.0
          Platform: PC-x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: trivial
          Priority: P2
         Component: -unknown

The "thumb" in the scroll bar's of DC++ (version 0.706 and 0.707) Notepad Frame
can initially start the wrong size, but moving it makes it turn to the correct
size. 
To replicate this, open up DC++ in wine.  Open the Notepad Frame.  Put in about
7 vertical scrolls worth of text.  Close the Notepad.  Re-open. 
After re-opening the notepad frame, the "thumb" is tiny, after scrolling it
changes to the correct size.
