I can only report that I came across this behaviour soon after I upgraded to Mmm 4.0. (PowerBook G3 233 mhghz, 160 Meg RAM, MacOS 8.6) and a few times after that. I intended to report it but could not find a way to reproduce it (and still can't). I had the impression that the bug tended to happen after clicking on the zoom box in a notebook window but of course only under some very special circumstances, which I could not isolate. Curiously I have not experienced it for at least a week now. -- Andrzej Kozlowski Toyama International University JAPAN http://sigma.tuins.ac.jp http://eri2.tuins.ac.jp ---------- >From: dreiss at --NOSPAMscientificarts.com (David Reiss) To: mathgroup at smc.vnet.net >To: mathgroup at smc.vnet.net >Subject: [mg18999] [mg18955] Help tracking down a Bug >Date: Fri, Jul 30, 1999, 6:33 AM > > [Moderator: this doesn't seem to have made it oo > to the comp.soft-sys.math.mathematic after having posted it > several days ago so I am reposting it.
