Mouse/focus problems on Mac

[Wes Mitchell]

I'm having some usability issues. Downloaded the latest kstars 
(kstars-3.5.9-1375-macos-64-clang). As soon as the mouse pointer enters 
the main window, the window starts to zoom in, and doesn't stop. Also, 
the scroll bars are funky. For example, in the main Preferences window, 
if I try to scroll to the bottom, it doesn't "stick", just reverts to 
position. Almost as if the program is receiving a constant stream of 
mouse events, or scroll wheel events.

My mouse seems to be working normally elsewhere :)

Thanks
Wes
