Mike,

No, I think you understood where I was heading. It isn't making sense. There

was an odd behavior seen once in my application that I've not been able to

take the time to track down. It is related to VFP 9 SP 2 runtimes on my

compiled with VFP 9 SP 1. I've not been able to make the time to track it

down since most clients are not running that configuration. It has something

to do with a loop process and updating records in tables. No ActiveX

controls involved, so the scenario is only similar by the SP 2. As I'm

typing, I recall it was happening on XP workstations too. I don't have any

more direction.

Since VFP 9, you can capture the coverage profile logging on with SET

COVERAGE TO... in the runtime.
