My platform:
Eclipse 3.4.1 linux_x86_64
swt (x86_64 version)
I've installed the necessary dependencies for Visual Editor:
JST
EMF
WST (installed by default in 3.4.1)

My Problem:
After creating a new project, and adding a new Visual Class, when I create a SWT Shell, all I can see is a small black box in the Visual Editor. This box can not be resized, nor can I place any controls on it.

Has anyone else had this problem and/or offer a solution?

I hope this is not a bug in the 64bit platform, but I can't seem to find (after googling all day) anyone who has had a similar problem.

Hopefully I'm just missing the obvious here....
