[Mono-winforms-list] MessageBox is working.. WinForms not

[Juergen Moeller]

Hello,

after a completely new installation of mono, I tried to build a very little 
SWF-Application...

the code:

using System;
using System.Windows.Forms;

namespace MyFormTest 
{
	class SWFTest : System.Windows.Forms.Form
	{
		public static void Main(string[] args)
		{
			MessageBox.Show("msgbox...");
			Application.Run(new SWFTest());
		}
	}			
}

The MessageBox is shown! But after clicking the OK-Button of the 
MessageBox, I get the following error:

Unhandled Exception: System.ArgumentException: Invalid Parameter. A null 
reference or invalid value was found.
in <0x0007d> System.Drawing.GDIPlus:CheckStatus (System.Drawing.Status)

in <0x0004f> (wrapper remoting-invoke-with-check) MyFormTest.SWFTest:.ctor 
()
in <0x0002a> MyFormTest.SWFTest:Main (string[])

So, there seems to be an error in System.Drawing??? 

I compiled the little test like that:
mcs -r System.Windows.Forms SWFTest.cs
mcs -r System.Windows.Forms -r System.Drawing SWFTest.cs

Both methods produce the same result. In the first method, is 
System.Drawing included automatically by System.Windows.Forms? Because the 
exception happens everytime in System.Drawing.

I have installed following form CVS:
mono 0.91.99
winelib
libgdiplus 0.6

and Wine-20040505 from a tarball

on a SuSE 9.0

Where should I search for the error?



Thanks,
Juergen
