[MonoDevelop] Closing dialog windows from my addin freezes MonoDevelop

[Scott Ellington]

I tried something to the effect of this:

void MyUriHandler ( object sender, OpenUriArgs e )
{
	GLib.Idle.Add ( new GLib.IdleHandler (DispatchToUi) )
}

bool DispatchToUi()
{
	Runtime.Gui.CommandService.CommandManager.DispatchCommand
				(FileCommands.NewProject);
	return false;
}

The app still hangs on closing the dialog.  Let me know if this is not
what you meant me to do. thanks,

Scott
