Hi Tom,
I did try this with an earlier version (around Jan 2001, I think). I
attempted with the newest versions and got the same error. I also
downloaded your prepackaged stuff, but haven't installed it yet. Since
it appears the problem wasn't an obvious one, I'll dig around some more.
I am glad to see that Attempt #2 should at least work ... :-(
Thanks for the quick response.
