One rather well known program which did not reset the the desktop in early
versions was the Kuma Resource editor. There was no problem in using as the 
offically sanctioned way to crash the system (see above quote from mui@atari)
just by starting it from one of the many GEM-menu based shells (the AES really
likes drawing non-existant resource trees).

This information, plus the fact that there was/is an undocumented workaround
(using an address of 0 to reset) and a suggestion that Atari document this
behaviour was posted by me to this newsgroup in early 1987/late 1986.
