I also was unable to stop ACL5.01 without killing Lisp entirely, until I 
discovered (somewhere in the Allegro documentation) that if you right 
click on the small Franz icon down in the lower right corner, one of the 
options is to interrupt (I think) which immediately stops whatever is 
currently happening, but doesn't kill Lisp, so your program files are 
still there. I discovered this after I had a Lisp program which was 
running much too long, and I found this way to stop it. Hope this helps.

  One other question:

  I've asked this several times, but the suggested solution never works:

    When running Allegro in Windows 98, I can't find a way to break my 
run without terminating Allegro itself.  This has become a real pain 
recently, since I'm debugging some pretty hairy code which frequently 
goes into hyperspace.  I have no problem halting stuff in Unix, but in 
Windows, the usual use of the Break key just isn't enough.  I have to do 
cntl-alt-break to get any interrupt, and then my only option is to kill 
lisp itself.

  Cheers...
