Steam: Lockup, forced to restart computer

[katrazy]

any info on the progress of a fix for the complete computer lockup for steam 1.7 users. once again it looks like a texture malfunction (random split triangles of varying colors) and it occurs at a random time after we've been playing. Its made the game unplayable for almost a month now, even if it is only a handful of us. ANY eta would be appreciated
