Are you executing an Application.quit method on the Excel task before clearing the pointers?

I was trying to troubleshoot a user complaint, and noticed that they had a ghost instance of Excel. When I stepped through the code, I noticed that the timing of the "death" of the instance didn't coincide with the setting of the final pointer to Nothing. When I did a simple test procedure that started and terminated an Excel instance, I noticed that the instance died immediately upon setting it to nothing. So it leads me to think that the user's complaint might be related to the way the objects are being terminated. I don't understand much about that (though, thanks to your help I now understand more) so I raised the question to the experts. Thanks again for taking time to respond to my musings . . .

I mean if MS Excel instance does go away - that's OK IMO, and everybody should be happy even without setting all the pointers to nothing :)... What am I missing?

And yes, I was watching the processes tab of the task manager. I was careful to make sure that there were no Excel instances present before running the procedure. As I step through the part of the code that cleans up (closing workbooks, quitting Excel, setting pointers to Nothing, etc.) the instance remains on the processes list. Only upon execution of the "Exit Function" line of the procedure does the instance disappear - but the instance DOES go away, it doesn't remain a ghost. I suspect that I'm overlooking a pointer somewhere that needs to be set to Nothing. I thought I got them all, but maybe not . . .
