[Mono-winforms-list] Messagebox error

[Paul Johnson]

Hi,

I'm using MWF built about 20 minutes ago from svn. My understanding is
that MessageBox should be working happily now. I'm getting an error when
I run this code

using System;
using System.Windows.Forms;

class Sum
{
  static void Main (string [] args)
  {
    int sum = 0;
    for (int n = 2; n <= 100; n += 2)
      sum += n;

    MessageBox.Show("The sum is " + sum,
                    "Sum even integers from 2 to 100",
                    MessageBoxButtons.OK,
                    MessageBoxIcon.Information);
  }
}

mcs sum.cs -r:System.Windows.Forms
mono sum.exe

#region #line XplatUI Constructor called

System.Windows.Forms.MessageBoxIcon)
in <0x00058> Sum:Main(string[])

This looks either an underlying problem but it is more likely some sort
of odd behaviour from MWF/MessageBox. Does this need entering into
bugzilla?

TTFN
