[Mono-winforms-list] WinForms on Linux/MacOSX

[Euan MacInnes]

Hi,
   As part of the application I'm working on, cross platform between Windows/Linux/MacOSX, I'm having an error with the Linux/MacOSX implementation of WinForms that I'm not seeing on Windows (using Mono on Windows). The error comes in creating a form in a spun-off STAThread, where I get this error:

type: 10 Not implemented

Hope this info is useful. I'll try a build without icons on it to see if there's any better luck.

Cheers,

Euan.
