Summary: Weird buttons behavior - just sometimes clickable (10%)
           Product: Wine
           Version: 0.9.18.
          Platform: Other
        OS/Version: other
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-gui

        ReportedBy: [e-mail]

The side toolbar buttons in SWiSHmax exhibit very odd behavior: when the cursor
is over, they quickly witch between ative and inactive state with every mouse
move. If you try to click on them, it's like playing a roulette - if you're
lucky enough, the button switches to the selected state, but most tries will
fail (I believe, they are clickable only when in active state (3d effect)) You
can see a short video, where I'm trying to click on the bezier tool button on
http://public.toh.cz/funky_buttons.mpeg but the framerate is low compared to the
button blinking frequency. The same problem applies to most checkboxes in
SWiSHmax. No information goes to the terminal, other applications seem unaffected.
