	That is very odd.  I tested that exact case with double quotes
and a file with lots of 'FOO's in it, and it worked fine.  Something
else you're doing is causing the double quotes to not work the expected
way.  Maybe your pattern has a '$' in it?

	You could try this:

cat file | sed -e 's/FOO/'"$FOO"'/g"

	Again, if $FOO has a '/' or '\' in it, it won't work right.

Have fun (if at all possible),
