Hello,

You should start trying to use Woden and Woden-Roassal. Everything of
Roassal 3D will be moved to Woden.
http://smalltalkhub.com/#!/~ronsaldo/Woden . To install it you only have to
run this script:

Gofer new smalltalkhubUser: 'ronsaldo' project: 'Woden'; package:
'ConfigurationOfWoden'; load. (Smalltalk at: #ConfigurationOfWoden)
loadBleedingEdge
In Woden I have many bugs to fix, which I havent because I have been busy
the last month making the new FFI.

I have still problems with NBOpenGL with an ATI Radeon HD 4250
> Graphic card

What graphic driver do you have? AMD stopped providing support to the
graphics cards older than the HD 5xxx, If i remember it correctly. I guess
that you are using the open source drivers.

Greetings,
Ronie
