Hi Mark,

You're welcome, however, I simply discovered it trying to fix my own class browser, so I really didn't go out of my way with this.:-) As a matter of fact, if I hadn't done a search here trying to find the answer, I wouldn't have discovered your post.

In the next day or so, maybe I'll add this to the UT Knowledge Base. I don't know if this is addressed in SP3 or not, but it's good information, nevertheless.
