Hi all,

I've got an application with an alarming number of users reporting
force closes. I've tested multiple devices numerous times and never
had this happen, so it's very difficult to test. Luckily, the new
stack trace reporting features seem to give me an idea, but I am not
familiar with "ANR keyDispatchingTimedOut" and Google doesn't seem to
be much help. I can debug when I see the error just fine, but I'm not
sure what information these stack traces are providing me. Is it just
saying where each thread "was" when the crash occurred?

Any help would be greatly appreciated - not just by me, but by a lot
of my users!
