[Jeremy Faden]

There's a new hang after the changes to fixLayout. See the stack trace created via "jstack PID > outfile":

I'm not sure why actions besides "moveLegendsToOutsideNE" don't hang the same way, but I'm turning off this for everybody on the event thread.

[Jeremy Faden]

I'm not marking this as fixed until I'm convinced there wasn't a good reason why there was locking and until I understand why only the "move legend" action caused the problem.
