pcxset crashing

[rgodbey]

I cannot find much in the way of pcxset documentation/support.  We have a couple computers that will crash intermittently and sometimes quite frequently, with pcxset.exe as the faulting app and ntdll.dll or spengine.dll as the faulting module.  I have been digging deeply but have not had success finding a solution.  PCs are running Windows XP sp3.

Here is an error from Dr Watson log:

The application, C:\Program Files\3COM\NBX\NBX pcXset\pcxset.exe, generated an application error The error occurred on 05/21/2010 @ 16:38:04.341 The exception generated was c0000005 at address 7C91B21A (ntdll!RtlpWaitForCriticalSection)
