Hi Bill,

Welcome to ASPNET newsgroup.
From your description, after upgrated to asp.net 2.0, one of your asp.net
page will always throw some validation exception when running, yes?

Does the exception always occur only when you postback the page? Also, from
the page's aspx and codebehind, can you find any particular changes in it?
Based on my experience, since ASP.NET 2.0 use "EnableEventValidation" by
default, so if you page programmatically output some clientside script for
post back or write out some html form elememt, there'll raise such
validation exception when post back.... You can try turn off the
"EnableEventvalidation" in @Page directive to see whether it helps...

If there're anything else you found, please feel free to post here also.
