Seems to work for me too, so it must have been OS 9. It's been a few 
years since I had to use this.

Wish I could test it on Windows for you, but my Windows machine is 
unavailable for a few weeks. But someone else said it worked in WinXP -- 
which is weird, if it isn't working on your machine. Could your machine 
have caught a virus/keylogger (or would that even interfere?) Or do you 
have some macro thing installed, or anything?
