My two screens were both 1600x1200. I never tried using sawfish-client as I'm unfamiliar with its use. The problem was so prevalent for me (at least 5 times during 8 hour work day) that I was forced to change over to KDE. I hadn't realized until this change that kwin offers nearly all of the features that I had grown dependent upon with sawfish. As much as I saw this problem, I had never pinned it down to a specific cause. Changing workspaces with the GNOME pager did seem to cause it more so than any other event, although other events indeed also caused the problem.
