GWT is crashing my browsers on Debug mode, anybody has a solution?

Following StockWatcher tutorial,

http://code.google.com/w开发者_运维技巧ebtoolkit/doc/latest/tutorial/debug.html

When I run the app in debug mode, my Safari or Firefox becomes irresponsive (I can't even switch to them). If I stop the debug mode from Eclipse then everything is back to normal.

I have a MacPro with SnowLeopard, and this is my Java. Google Eclipse plugins are up to date.

dvr-2:~ devrim$ java -version
java version "1.6.0_17"
Java(TM) SE Runtime Environment (build 1.6.0_17-b04-248-10M3025)
Java HotSpot(TM) 64-Bit Server VM (build 14.3-b01-101, mixed mode)

Could u advise ?

Updating to the latest GAE SDK and GWT version solved it. My browsers weren't only appearing blocked, it was crashing: u.kodingen.com/zgO5Y
