I think I've found a solution, working on it!

I attempted to override the symbol shell by the following patch:

/System would be no operation as expected, and the terminal no longer messes up. But, once inserting the call of system(3), I found something wrong, and Lotus 1-2-3 program complained the following:

Error loading driver, file name - /proc/self/cwd/root/lotus/123.v10/ri/USA-English/dr123txt.ri

I think this might be an old bug, can you try rm ~/.l123set and see if it fixes it?

I also updated it to enable UNIX file mode by default.

I can reproduce the orginal issue, as you say it almost works, messes the terminal up.
