Sounds like you may be experiencing issues specific to your system. I don't know what kind of system you have, but regardless of what OS you run a good first step is always to shut down your system; unplug the PS from the wall; remove the battery if it's a laptop; give it a minute and restart it and see if it made things better.
Audiogon is the only forum I know where unpublished posts just disappear if you leave or refresh the page. And then, sometimes the site makes refreshes the page on it's own, or it decides that you need to login again when you just happen to be in the middle of a post.
By contrast, write a post on DIYAudio but don't publish it; close your browser, turn the system off, whatever, when you reboot your post will be there waiting for you.
Why Audiogon persists in not using any of the excellent forum software out there and going their own way instead is beyond me. I guess, in a way, it's admirable; but if you're going to do this, then make it work.
