1.) copy VMERRTR.DLL to your Smalltalk directory
2.) FileIn 'tkbvmerr.st'.
3.) enable the DLL by evaluating: 'TkbVmErrorTrackingDLL enableExceptionHandler: true'.
4.) save the image
5.) activate the exception hook by evaluating: ''TkbVmErrorTrackingDLL startUp'.

Repeat step 5 at each image startup (if necessary).

If a GPF happens while the exception hook is active, you will get
a file named "stack.dmp" containing information about the Smalltalk
stack.
