I've been having a screensaver problem recently and after searching on here and other places I haven't been able to find anyone who has a similar issue. My issue is that my automatic screensaver has stopped kicking in. I have it set to start after 15 minutes of inactivity but it just never happens. However, my hot corners will start it just fine. I have repaired permissions on the drive and that didn't do the trick (obviously because if it did, I wouldn't be posting ). I'm running an Intel Mac 3GHz dual core Xeon with 10GB of memory. I'm sure it has something to do with the upgrade I recently performed. I upgraded from Leopard to Snow Leopard and after doing so I SuperDuper'd my drive to another drive and am using that. Any suggestions are appreciated!
