FreeBSD and filePro weirdness

[Brian K. White]

Switching to bash seems to have fixed it.
I had to change some things to be more generic, but then I could try 
different shells at will, and so I flipped back & forth between ksh & bash 
several times and repeatedly demonstrated the effect, and then lack of 
effect, several ties in a row.

start with ksh, run it, break, blam
run again, break, blam
change it to bash, run, break, no blam
run again, break, no blam
change back to ksh, run, break, blam

Sill a puzzle though why the other scripts that do the same thing on the 
same box don't have the problem.
The ksh is the real korn ksh93 compiled by suse and provided as a package in 
the software manager.
