[Mono-list] I think I've found a bug. Can anyone confirm or clarify?

Something immediately strikes me as wrong: you're mixing GTK# and
Windows.Forms. In your earlier message, I thought this was a WinForms app.
You need to pick one or the other. :)

However, note that Mono / MonoDevelop doesn't have a WinForms designer. So,
if you want to use a GUI designer, either use WinForms on Visual Studio /
SharpDevelop (your exe will still work with Mono), or use GTK# on
MonoDevelop (note that GTK# apps will require an extra 8MB installation to
run on Windows).

Good luck!
