I'm using FronPage 2002 and also, depending on ftp connection to server, get hung up/timed out now and then. The best thing to do is to set your options in FronPage to only update changed files. This way, if you only make it part of the way through the transfers, you essentially pick up where you left off.
Anyhow, that's worked well for me. Mind you, I've only been at this for a couple of days now, but the site's up and running so something must be going right
