Automatic Logout / Session expired

I am having a problem when I delete a folder.  When I right click on the folder and select delete I get a message saying "An error occured: Your session has expired, please login."

Can anybody suggest anything?

Thank you
Jeff

I have the same error with our installation as well.

Anyone?

This is a feature of ASP.NET 2.0. Whenever a subfolder within the application's root folder is deleted the application domain is recycled.

So you should use root folders outside the application. For instance, if your application folder is /FileVista, you should not use a subfolder like /FileVista/Subfolder as a root folder.
