Hey All,
  I have a playaround site that I have been using to learn about ASP.NET
2.0. I wanted to see how it renders on a PocketPC that a friend has. Some
pages work, but most I get a viewState error.
     "Invalid length for a Base-64 char array." (below is the full stack.)

   I googled, and didnot come up with much at all. I did change my config
file to explicitly not encrypt the viewstate, and that didn't help.

Is there something oblvious I missing here?
Is there a setting on the PocketPC I need to set?
The .NET controls should render for PocketPC and smartPhones, right?

Thanks
Eric
