Thanks Boreas, that explains a lot. Part of my problem was that I didn't know the terminology to use to ask a question that made sense to you folks who know what you're doing.

I'm using M3 as my theme.

Hmmmmmm. I did a search through the \Litestep\profiles\me\themes\M3\ folder for lsxcommand in any *.rc file and found nothing. I also don't see anything like it mentioned in theme.rc or themevars.rc at all. I wonder if this theme doesn't have it installed.
