Windows.Forms under IronPython

New user of mono through IronPython just joining the mailing list. I've
read some of the getting started docs with mono and winforms, and looked
over what has been implemented, but didn't an answer to the following
problem. I'm running mono on Linux out of CVS with latest FePy:

Thanks, that was it. It wasn't clear that this needed to be the case 
from the mono "getting started" pages.

Wow! This is great: IronPython (with graphics) running on Mono on Linux. 
It is stunning to think of the diverse groups of people that have all 
contributed work to make this possible.

(FYI, I'll be producing some code, examples, and documentation this 
summer about how to use this to control robots. For more info, see 
http://wiki.roboteducation.org/ )

Thanks again!

Hello,
