No, I haven't found a new issue. But one that seems to be an ongoing issue with APC.

It seems that they haven't updated much since 10.4.8
and people have issues with UPS devices. I need one because I get 1 second outages monthly and a flurry of foul language spews from my mouth when it happens. I'm hoping a $50 item will do the trick for me. But have any of you had the issues listed in that MacWorld article? Alternative company perhaps?
