    I have a RadScriptManager on a form along with a RadGrid.  I have an issue where 2 users (both with IE7 browsers) are able to populate the grid fine on their first try, but then sometimes have issues on subsequent attempts. There is a ‘Refresh’ button on the screen and it’ll usually work, but fails intermittently (usually after they’ve waited some time to refresh the report). 

    I’m not able to recreate on my IE8 browser and the users currently don’t wish to upgrade from IE7.  Is this a known issue with IE7 and ScriptManager?  Is there any resolution to this issue?  This is the exact error that the users get:  “Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500
