Howdy Jim,
 I did post for this problem on FC3 a couple of weeks ago and Fielder
came up with something along those lines. I'm currently in the middle of
upgrading to FC4, and I have his email saved on cd for future reference.
Those are good tips also, look forward to checking my USB and if I have
the same problem I'll definitely be using both Fielder and your tips.
Thank you and take care, Bob.
