Bruce,
I actually verified this pretty quickly by just testing and canceling
the post a couple of times. The error happened if I waited a bit then
canceled the post, much like a user would if they were sick of
waiting. The amount of these errors means that we are really pissing
people off! I'm going to work on cutting down the viewstate
immediately.

A note to everyone: Do not use webcontrols for static content without
setting EnableViewState to false!

Alvin, thanks to you too. Now you have seen this before!
