I'll try again on a Win2K server. Slap on the wrist for not checking the docs - in my defence I'm recovering from a rather nasty cold, and I am following on from someone else's reported problem!

Since I trust Dave, I feel that the above is an accurate characterization of the situation. Jason

No slap is necessary. I'm sorry that my terse response did not indicate my appreciation for taking the time to help out. Thanks, Jason
