Occasional GUI partial lock-up problems

           Summary: Occasional GUI partial lock-up problems
           Product: JMeter
           Version: 1.9.RC2
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Main
        AssignedTo: jmeter-dev@jakarta.apache.org
        ReportedBy: tjsb@slb.com


Certain sequences of operations on the test tree seem to cause the GUI to stop 
responding properly - right-click does not work, and only some of the menu-
items work. Also the GUI does not repaint properly.

I've seen this after disabling/activating listeners in a simple JavaTest 
sampler test script.

Unfortunately, I don't (yet) have a simple test case - it has only happened 
after quite a few changes to the test tree.

I'm hoping to be able to provide a test case in due course.

The first part of the log is as follows:

The rest of the log seems just to contain further NullPointerExceptions, which 
seem to be output when further GUI events are generated.
