The window server is not perfect, and malicious / unusual / flaky PostScript can tip it over the edge. Of course, when the server dies, so do all its clients. I can do this relatively easily from pft or yap, but it isn't always reproducible. TopDraw does this quite frequently as well. (Want to really have a blast? Try resizing an AppKit-managed window from within pft. It does interesting things...) -Anthony
