I have noticed a similar problem/feature when running Wordstar.
I tried the 8080 version of Wordstar, which works fine on a
Z-100 under CP/M-86. Just like Final Word, it
ignores characters typed during loading of the program,
and the OS ignores those typed while exiting the program.

The Z-100 has a hardware buffer in the keyboard, holding 17 characters.
The software buffer in the operating system (both ZDOS and CP/M)
is about 80 characters. All standard I/O looks in the software
buffer automatically.
