I'm using the latest version. I've checked that.
It worked fine until the last Update of the 3d-monitors. I've changed the new Radeon-driver (in Morphos:Morphos/devs/monitors/ Radeon(143.728 kb) with the old one (119.704 kb) and Showgirls worked again.
With some minor problems in the menu (some menu-items are ghosted until you have clicked in one of the others)

Strange!!!
