I have a simple WinForms app, which was created and complied under VS2010, it's
Form with button which show MessageBox on click. I tried lunching this under
Mac OS X 10.6.6 with MonoFramework-2.8.2_1.macos10.novell.x86 but mono crashes
with segmentation fault. Same happens if i try to call Form.ShowDialog(), or
try to open any child window... MainForm works though.
