It's been awhile and I can't remember the exact problem without looking up my own posts (possible one of the old ones you found), but I had enough trouble with alt in hotstrings that I switched software altogether. I expected Keyclone to have fixed it by now, but maybe it's one of those elusive bugs that's hard to pin down. I know that when I posted, I got some well-meaning responses but nothing that really applied to my problem, giving me the impression I was the only one. Hopefully you'll find that it is something simple, a typo in a macro or something bound elsewhere, but if you do narrow it down to the software, definitely make sure Rob knows.
