Sounds to me like you might be attempting to update the UI from a background thread. This is one of the symptoms.

   am working on a .Net project and our application randomly crashes with no
 exception being thrown. The application just disappears, like someone would
 have clicked the exit button. This occurs both when we are debugging and
 when the application is running after an install. I have been stepping
 through code and then just had the application stop and VS just goes back to
 normal, like I had told it to exit the code. I have read about a couple of
 other applications having the same problem, but have never seen a
 resolution.
 
 I have turned on catching of all exceptions in the debugger but
 it still seems to not catch what is going on. Any ideas on a way to find
 out what is happening? We can not reproduce it by any events, it just seems
 to happen while we are running the program, sometimes it will be hours,
 other times it will be 3 minutes. It does seem to occur more often, the
 more the application is being used. Meaning, just leaving the application
 on, but not working with it, does not sees to cause the crash as much as
 having someone working with the application.
 
 
 I have tried adding add a handler to
 System.Threading.Thread.ThreadException in our main.sub. This had no effect
 on catching anything.
 
 As I mentioed even turning on catch all excpetions in VS doesn't seem to
 catch anything, the application just quits.
 
 Any suggestions would be greatly appreciated
