[Qt-interest] Strange bug on OS X

[Nikos Chantziaras]

I'm using Qt 4.6.2.  On Mac OS X (10.6.3) I'm using the Qt SDK provided 
here:

   http://qt.nokia.com/downloads/sdk-mac-os-cpp

When I start my app on OS X, the first time I click on it, it does not 
get focus and this is printed on stderr:

   handleTabletEvent: This tablet device is unknown (received
   no proximity event for it). Discarding event.

I have to click a second time.  Why is that?
