===8<==============Original message text===============
Hi, Jan:

Thanks for the reply. I did check, and we are experiencing the same on
an IE5 machine. Since that's not been identified as one of the problem
browsers, I don't think we're experiencing the same thing.

I'm getting the popup a lot - maybe 3 to 4 times per page, due to the
different graphics and buttons and things. (Like I said, I'll get the
first few portions of a page, then a popup or two, then a few more
portions..).

Dave
