Viewstate problem

[Iain]

Hello

We are having some problems with apparent corruption of the viewstate data for the home page on our website. The site itself consists of many user controls which are displayed / hidden as required on one page, Home.aspx. Any ideas or suggestions most welcome. The message we log repeatedly is below.

If you modify the page while someone is using it, you
might get the viewstate message like below.
