Yes (er, no), qmax already told me he couldn't run it on one machine and we narrowed it down to 5.6.0.   Apparently, it runs on 5.03, 5.04, 5.05 and 5.6.1!   If I get a chance to snag a copy of 5.6.0 to install, I'll see if I can figure it out.   Also, It won't run on 5.01 (and I guess 5.02) because it's using (?<=.) in a regex. Sorry. :-(
