There was also a floating-point emulator bug (system may panic after an
'exec' if there is no 80287 installed AND floating point was being used),
which has been fixed. The game 'phantasia' was the first to cause this 
panic on our system (3 panics in less than two hours! Removing the 'exec' 
from the die() code 'fixed' it temporarially).

There was also a problem in the system-vision package, make sure you obtain 
this disk as well if you use this part of the package (editing user 
defaults causes a core dump)

These have been fixed, and V2.2.2 is available. I would advise all who have
2.2 and do not have an 80287 to contact Microport to obtain this update.
We have received this upgrade and it does appear to correct the problem.

Note: 2.2.2's release notes still list the 80287 bug as an open problem.
