[Mono-list] Mono Error

[eschneider at schneidersoft.com]

The problem seems to be with this code:

                            Dim bm As Bitmap = New Bitmap(m_Image)
                            bm.MakeTransparent()
                            m_Image = bm

Hello,

I'm trying the latest mono and I get the below error when running on Mono 
2.4 & WIN XPSP3.

Looks like it has something to do with drawing or bitmaps. The Program runs 
fine in Windows/MS.NET.
I also tested the app on MOMA, it did not show anything for this.

Maybe there is a easy work around or a different overload I could call?

Thanks,
Eric
