If you are running Fedora Core 2 with Sawfish as your window manager, and you notice that when you click on workspaces in the pager your windows jump around randomly, there’s an easy fix to get it working again:
Download the source code to libwnck, build it, and install it on top of the rpm Fedora Core 2 provided to you. This was an old bug that was fixed long ago, but for some reason the RPM of libwnck still has it.
