Hi, tlhawkins!
I've been running 5.0 since it was released, and I haven't had any problems with it. My site is a fairly simple intranet (growing more complex daily!), so this might not be a good indicator. It does, of course, have a few more bells and whistles which I haven't tried except in a couple of small test pages. Anyway, I don't think you'll have any trouble with it. I don't think there's been many complaints about it on this forum, but maybe there just aren'y that many people using it, yet.
Oh, well, that's my $.02 worth. Calista :-X
