The refresh is needed because the interface uses the Internet Explorer cache to
store thousands of little XML files.  Seems to me like a dubious process, but nobody
asked me.

Huh? So if someone cleared his or her IE cache - or has it set to do so on closure.. you'd end up with an empty Poser library? Until it's refreshed at least?

You just can't put the words "Poserites" and "happy" in the same sentence - didn't you know that? LaurieA
