Re: Weird display problem

One more note-

If you can toggle any layers on and off then there is no

DisplayImpl.java).

I agree.

A good way to analyze deadlocks is to run under jdb. When
you think you have a deadlock, enter the jdb commands
'suspend all' and 'where all'. This will give you a stack
dump with line numbers for each Thread, and you can see
where Threads are waiting inside synchronized() {...}
statements.

You can also get a thread dump at any time by:

- pressing Ctrl-Break on Windows
- sending a kill -QUIT <pid> on Solaris and linux or ctrl-/
