10. Dr Watson PostMortem error :

Can you check to see if Dr Watson is configured as the default debugger?

In the registry, check:
HKEY_LOCAL_MACHINE\Software\Micros­ oft\WindowsNT\CurrentVersion \AeDebug

The key will be called: Debugger and the value will be something like: Drwtsn32 -p %ld -e %ld

If so, perhaps remove that key, and see if that solves the problem (if Dr Watson crashing is causing the lockup). If you are still gettin the lockup, then the problem is somewhere else (e.g. the original NJStar problem). Try uninstalling that application.

If you need to reinstall Dr Watson as your default debugger, run:
Drwtsn32 -i
at a command prompt
