[Gtk-sharp-list] GTK# app "hanging"

[Raúl Moratalla]

Thanks for your info Jon but I have the following question.
I added a line like this in my program:

Gtk.Timeout.Add(0,delegate{m_Log(this,importance,strMsg);});

If I compile my program I get the following error:
Not all code paths return a value in anonymous method of type 
`Mono.CSharp.AnonymousMethod'(CS1643)

What am I doing wrong?

Cheers,

Raúl
