[Mono-dev] Managed.Windows.Forms locks X11 up

Notepad works fine for me. But youre' not really giving much detailed 
information about versions you are running. I use svn head+ on libgdiplus 
and mcs. You can also try all the testapps in the winforms module, for 
example wordpad, to see if that does the same.

We fixed a few possible X lookup situations not too long ago, maybe you're 
running into that.

Also, winforms issues probably find a better audience at 
mono-winforms-list at lists.ximian.com
