Oleg,

Thank you VERY VERY much! Your suggestion worked! You have save me so much 
trouble (reinstalling Win2000 and all of my applications).

I had made this change as recommended by 
<http://web.ukonline.co.uk/cook/Memory.htm>. I'll send them a note ASAP 
letting them know this unfortunate side effect of their memory management 
optimization.

Thanks again!

- Daryl Forrest
