The above report was under Dapper. The problem still exists in Edgy and in fact seems worse. The gnome-panel still seems to be affected the most often, however the old work around of killing gnome-panel (so that it could restart and be visible) tends to make nearly all other windows disappear. Like before, the windows that disappear still have their process running, but there is no way to make the window visible. Affected windows disappear from the desktop and the window list applet. In short, sawfish is almost completely unusable with Edgy using Xinerama.
