Stepping excludes

Hi,

I am using Jswat 4.2 with Windows xp, running under java 1.602. When I debug a
program, it often trace to source code ClassLoader, Object... I do not need to
trace into these classes, so I went Tools>Options>Stepping Excludes to specify
these classes. After that, things got worse: Jswat still traces into these
classes, but does not show these classes, so I do not know what was happening.

I went Tools>Options>SteppingExcludes again to remove all about classes. These
classes disappear on the list, but Jswat still traces into these classes
without showing these classes.

I went to Session>Settings>Sources to remove c:\j2sdk1.4.2_14\src. But later it
is added automatically be JSwat.

How can I:
1. permanently remove java system classes from Settings>Sources?
2. tell Jswat not tracing into classes which source path is not specified?

Any information would be appreciated. Thanks in advance.
