Hi fellows

I've done this simple test in order to help knowing if this is a bug or
just lammeness :)

The problem is that Gnome.CanvasWidgetshould be appearing on the
Gnome.Canvas and it isn't.

I'd love to know how to add an Gnome.CanvasItem to the upper-left corner
of the canvas, since I'm unable to get it in my tests with

I'm using Mono 1.1.4 and latest gtk-sharp svn revision.
I've compilled and ran the test as follows:
mcs -pkg:gtk-sharp,gnome-sharp test.cs
mono test.exe

Thanks in advance,
Paulo Pires
