>>My computer (XP PRO sp2, 1 Gb RAM and 2,26 Ghz) really slows down after exiting VFP 6 and the only way to recover is to reboot.
>>Two unrelated scenarios cause this to occur:
>>1. One or more VFP errors since the last reboot. The computer runs progressively slower after each error. This has been occuring for years.
>>2. A program that I am testing now packs and copies about 250 tables. Two of the tables are > 200 mb and one contains about 1.7 million records.

In regards to scenario #2 which is one self contained program:
No, I am not using chrtran() at all.
I start VFP, start the program from the command window and then exit upon completion.
It does not invoke any other programs, etc.
Should the two lines of code be literraly at the start before any 'locals', etc?
