[Mono-winforms-list] Re: Problems with Button........

[Peter Dennis Bartok]

Seems you are running the 'discontinued' wine-based system.windows.forms 
assembly.
Check out http://www.mono-project.com/contributing/winforms.html  to see the 
details and how to build the newer implementation. The new implementation 
will become the default in the near future, but since we are still missing a 
few controls it is not yet.

Cheers,
  Peter
