You're right. gtk-sharp has a Winforms dependency on the Windows
platform to enable visual styles by calling
System.Windows.Forms.Application.DoEvents via reflection. Nobody has
ever found out why this works or how we could implement such
functionality without loading winforms.
We should probably put that code in a try-block. What do you think, Mike?
