..etc...
In some measure, this depends on the particular version of Zip. My OS/2 port,
for example, has no problems with Bureaucracy. The MS-DOS version that was
extant at the time I was doing the port did have a problem. There is a newer
MS-DOS version now (designated 2.03 -- it is the only "2.03" version of
Zip that exists) that I understand has fixed it, along with several other
keyboard and display problems that only involved one or two games, all of
which my OS/2 version also fixes. I know nothing about other versions.
