I keep getting the error "HTTP Request specified an invalid port number" in Fiddler.

It looks like the problem is that Fiddler is appending a "1" to the front of my port number.

The address I am plugging into my web browser is http://ourlocalserver:14485/api/...

This works fine when Fiddler is not capturing traffic. As soon as I turn Fiddler on, it starts failing, and Fiddler logs the address as http://ourlocalserver:114485/api/...

Notice that the port is now 114485 instead of 14485.

How can I get Fiddler to stop modifying the port number so that my tests work correctly?

No answers yet. Maybe you can help?
