I can reproduce this but not reliably (some times it crashes, sometimes it doesn't). But I always get this warning everytime I click on the sprite: Thu Jul 21 14:15:09 myhost.ottawa.ibm.com java[961] <Error>: kCGErrorIllegalArgument: CGSGetWindowBounds: NULL window Thu Jul 21 14:15:09 myhost.ottawa.ibm.com java[961] <Error>: kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to catch errors as they are logged.
