That's not inevitable.  I think that there is almost certainly 
something else at work, e.g. use of document.write and/or
pages with inadequate cacheability (form output is considered 
relatively uncacheable by default, but may well be privately cacheable
in reality).  POST output is considered less safe than GET output.

Lynx definitely allows one to come back without resetting the form and
I'm sure that I have done it on IE, and possibly NS4 (just confirmed
it for NS4).  (One reason I don't have the problem may be that I turn
of Javascript.)

I can't try much out just now, but I would check the results of using
static forms, using redirect to GET (might be status 303, but I'd have
to check) where a page of a multi-page form contains no content from
other pages that is not in the URL (possibly just as a serial number
to make it unique), removing document.write's, sending Cache-Control
headers giving some private cache lifetime, etc.
