Summary: Scroll bars don't scroll properly with thumb in Altium
                    DXP2004 sch view
           Product: Wine
           Version: 0.9.30.
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-gui

        ReportedBy: [e-mail]

The horizontal and vertical scroll bars will not scroll the zoomed schematic
view in Altium's Protel DXP 2004 when dragging the scroll bar thumb. The view
will scroll properly when clicking the arrow buttons, however. I'm attaching a
debug trace of a scroll bar thumb drag, and then another clicking the arrows
instead. I used WINEDEBUG=+scroll
Both were generated while moving the horizontal scroller from the left-most
position to the right-most.
