Summary: Orange Box web browser scrolling messed up
           Product: Wine
           Version: 1.1.29
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

This is a regression from 1.1.28 to .29.

Oh joy: the Orange Box Store browser (first page up) now has scroll bars.
Alas: they're messed up!

On loading the browser seems to flicker between top and bottom of the
scrollable page, and when mousing over the scroll bars the scrollable tag
flickers from top to bottom.

Page Up / Page Down used to work, but now it looks like something is repeatedly
forcing the screen to the end of the page: can page up, but after a couple of
seconds the display is scrolled to the bottom again.
