Sys.InvalidOperationException

Jul 3, 2008 at 1:44 PM
 I downloaded the latest release v1.1 and I am having problems adding new widgets (Add stuff link).  I get the following error

"Microsoft JScript runtime error: Sys.InvalidOperationException: Type Sys.Timer has already been registered. The type may be defined multiple times or the script file that defines it may have already been loaded. A possible cause is a change of settings during a partial update. ".

I am using .Net framework 3.5 and VS 2008. I have googled for this error and there a couple of people who have got the same error message.
