Jim.
If you ever want to get into some slightly more advanced ASP stuff, then Frontpage is a pain in the ass. If you're using the WYSWIG editor then it produces bloated, innefficient code which doesn't help anyone with learning the language.
Even worse it can change existing code! which has to be the worst feature around, as well as the issue you've encountered.
I respect your opinion to work with what you choose, however after 8 years there have been many, many competitors overtake Frontpage (of which a number are free) and you'll find that as you hang around development forums like this one that FP has a shocking reputation, even from MS enthusiats like me!!
Anyway, my 2 cents. Good luck with your application.
Cheers,
Andrew
