Stop Press is/was a desktop publishing package for the Commodore 64 that came with the AMX clone mouse.  It's quite an amazing little program that has a lot of power and capability.  This is one to check out if you're thinking of making an old school newsletter.  Here a link to the manual.

*This is a PAL only program.  Even though it will boot up on an NTSC system, you won't be able to control the mouse.  Hint - If using a 1351 or CMD mouse press CTRL-4 to get control of the pointer.
