>I can't tell either with all the various and sundry stuff I load on my machine. I'm running Win98SE/IE5.0, and I believe I had it before I went out and installed the full package anyway. The only reason I did that was that I wasn't 100% sure what was what. Maybe the next MSDN library will have a KB documenting what files are what version and what installs what files. (This is getting me confused.)

Me too. I had it on two of my machines already, too, but I don't know where it came from, with my zillion developer components and test versions. But I did isolate it by watching the user machine yesterday. I've boiled it down to one of those two installs (Outlook2K and/or IE5.01), I'm pretty sure, as one way to get WSH2 installed.
