I must have done something wrong using XSI, and now, all my viewports have a black vertical line on the left hand side. That couldn't be that annoying, despite of the fact that I the shaded and textured view are all messed up. Don't know how to decribe it, it's like a non-shaded view, with all the edge (including the triangle edge in quads) visible through.
Can anbody help ? or is it a crash ? (when I restart, it's the same)
