Thanks for all the info! I didn't entirely get all of it, but it made
things a lot clearer than they were last night while I was staring the
code and scratching my head. I'll look into it more and probably have
more questions for you. I haven't tried the build option yet--I think
I've got 1.5.7a. Should I get subversion going and get the latest
