[Mono-dev] windows.form regression with mono 2.8.1

[matteo tesser]

Hi, I do not understood I'm the only one who suffers from this bug, or
is someone else experiencing it?

To your information, in my develpment machine I have setup a parallel
mono environment, but I do not think this causing side effects because
 I tried the sample in an power-pc mac and I obtain the same error.
