can't debug anything, can run stuff

Every time I try to debug a project I get NoClassDefFound.
I can run things fine, apps, applets, etc.


So, I made a new "hello world" project and tried the following:

Passing the same classpath that Run is using to the jvm.
Adding my output dir to my classpath (in project options.)
Renaming my JNIWrap.dll (a workaround for a similar bug in 801.)


I'm using build 701 on windows xp.
My target jdk is 1.3.1_07.

Thanks for any help.
