I did searches on this one...I'm using NNTP so it's nice...unfortunatly, no one had quite the same problem.
I had thought about the random value already (see paragraph about unique visit id), but it just seems like so much to keep track of... After asking on other board on the same topic, one theme seems to be the same...just use redirects. If anyone else is having the same issue, you can do a redirect using the PHP header() function to send the user directly to the next page. If the user goes back, they will get a new version of the form, and less browsers will support resubmitting. Also, on the same note, if anyone is using buttons as links, make sure you are using an <input type=hidden onclick="window.location='http://whatever'"> command instead of submitting a form with no fields. This will solve the problem here.
