Can't -Xmx above 768

Every time I up the -Xmx in idea.exe.vmoptions idea fails to start. I get a popup dialog indicating that the JVM could not start.

I'm using 1.6.0_01. I know this is not a jvm issue because I can start eclipse with 2G.

Here are my settings:

-Xms768M
-Xmx1024M
-XX:PermSize=256m
-XX:MaxPermSize=256m
-ea

Are there some issues the 7002 and configuring memory?

-bk
