trouble with viewstate

Hello,
I had a really weird problem that occured on one of our site. (occur 2 times
in 3 years)

The client 1 have fill the form1 and submit it, for some reason the page was
postback to the client 1 but the informations that was on the form after the
postback was not the informations of the client 1 but the informations of
another client (on another computer) that had filled this form 5 minutes
before.

we never save this information in any variables, enableviewstate have been
set to true to save the data on postback

here are some other informations:
Asp.net version 1.1
code vb.net
Framework 1.1, no servcie pack install
server = windows 2000 sp4
the page is ssl (https)
EnableViewStateMac is set to true on the web.configi'd suggest looking elsewhere for the cause. Probably the server is pulling
the wrong data based on id. It's unlikely for that type of thing to happen
due to viewstate confusion based on the way viewstate works.
