Ever since following the technique outlined in http://www.telerik.com/forums/how-to-automatically-re-enable-fiddle-as-system-proxy to get automatic reconnection, I'm running into occasional (once a week?) Uncaught Exception errors in fiddler.
error message with a stack trace attached, but the core of it is
Cannot access a disposed object. Object name: 'WinHttpAutoProxy'
Any advice for debugging?
