I've done a cvs update, rebuilt mono, rebuilt libgdiplus and tried to
run a winforms program which worked 2 days ago (though it did give a red

Today, I'm getting (this was produced by running a program with 2>out
after the program name - on screen it says something different [see

On screen I'm getting=20

  Resource id in failed request: 0x830582f
  Serial number of failed request: 22
  Current serial number in output stream: 22

Also, I'm finding that code such as=20

using System;
using System.Windows.Forms;

namespace WelcomeGUI
   class Welcome4
      static void Main( string[] args )
         MessageBox.Show( "Welcome\nto\nC#\nprogramming!" );

will compile and then instantly terminate without showing a MessageBox.

Has MessageBox been implemented or is it my system being silly again? If
it's my box, then fine other wise I think these should be in bugzilla.
