Losing Session Variables

When I delete a folder in the FileVista control, it clears all of my session variables.  As a consequence, users have to log back into the application.  Has anyone else had this problem? Please advise.

P.S. I am handling this event, but only logging it.  I am not doing anything that should be clearing session variables.

None of the other FileVista events are causing my Page_Load event to fire.  Why does the Folder_Delete event cause this to happen?  Additionally, why is this Page_Load not a Postback.

Some feedback this problem would be great.

I think I may found my problem.
