FusionDebug crashes after a while on Mac OS X 10.5.6 (Intel)

[FusionDebug newbie]

Hi,

I recently installed the FusionDebug complete IDE since I heard good
things about it. I've been using it for a couple of days and
everything seemed to work fine. However, right now when I go to save
a file the program just hangs. I don't know what's wrong since it was
working a few days ago. I'm using a MacBook Pro running Mac OS X
Leopard, with Railo as my CF application server. Below are the
messages I get when I Force Quit the application.

"The application J2SE 5.0 quit while unresponsive"

FusionDebug specific error message:

JVM terminated

Exit code=143
....

-Xms40m
-Xmx256m
....

Let me know if you need any more info. I didn't type in the whole
FusionDebug error message.

Thanks!
