#53 Workspace doesn't display anything

[Anonymous]

Archimedes starts and seems to work well. Commandline reacts, as well as menu items but workspace (openGL) is black or sometimes white and doesn't even display croshair. Saving and reopening drawings doesn't help. Resizing window results in artifacts (traces of redrawing) in openGl canvas.
I use Windows Vista 32bit and Archimedes 0.64.0.Shortcuts
