Hi Martin,

please file a bug against MD's bugzilla. IIRC, MD has an integrated

When running the app from within MonoDevelop the TextBox associated with the no_proxy value is empty. However, if I start xsp2 from the command line, both TextBoxes are displaying the expected values. I have always used the Debug build option.

It also means, that web apps which are using WebClient and it's proxy support will not work as expected within a debugging session of MonoDevelop. Maybe someone that knows more about the internals of MonoDevelop can fix this problem.
