[Mono-winforms-list] Oddball SWF problem.

[Paul]

Hi,

I'm using a bog standard OpenFileDialog with Mono 2.0 RC 1 (code below).
When I run the app, everything is fine until I go to the directory which
contains .spec files (these are plain text files used for packaging
under Linux).. it then goes kabloom with the following throwback (from
MD 1.9)

Unhandled Exception: System.ArgumentNullException: Argument cannot be
null.

The application was terminated by a signal: SIGHUP

Code which did the nasty....

8-->
		private string createDialog()
		{
			OpenFileDialog filer = new OpenFileDialog();
			filer.Filter = "spec files (*.spec)|*.spec";  
			filer.Title = "Select a spec file"; 
			return ( filer.ShowDialog() == DialogResult.OK )
				? filer.FileName : null;
		}
		
		private void button1Click(object sender, EventArgs e)
		{
			createDialog();
		}
<--8

Nothing nasty, it just doesn't behave!

Any ideas?

TTFN

Paul
