Even if the browser were to work correctly, you'd probably
get this behavior occasionally from users (in a network
slowdown, the user might click "submit" multiple times). So,
the best thing is probably to build for it.

How about embedding a random id into each form with
an 

<inputr type="hidden" name="form_id" value="&dtml-randomkey;">

and generate a random value for 'randomkey'.

Then check for multiple replies with same id in the script
you use to catch the data (means you'll have to cache
the ids somewhere).

Just an idea -- not sure how hard or easy it'd be in
your case.
