[AG-TECH] AGService development problem

[Thomas D. Uram]

Hi Ismail:

If you're able to reproduce this problem reliably, I'd like to know how.
I suspected I might know how to trigger the problem, but have so far been
unable to.  If it's a problem in current code, I'd like to get it fixed.

Thanks,
Tom
