U4-1378 - "About" dialog is broken

Created by Shannon Deminick 01 Jan 2013, 18:10:25 Updated by Sebastiaan Janssen 02 Jan 2013, 09:15:00

When you click on the About dialog we get a security exception. Not sure what version this started from but appears to be a medium trust issue. The URL is: /Umbraco/dialogs/about.aspx

the stack trace/exception is:

Server Error in '/' Application.

Security Exception

Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.
