After upgrading to Snow Leopard have been having the following problem:
When I go to bed, I set my mac to play an iTunes internet stream. I set the Dashboard widget "Minutes" to sleep my computer after one hour or more. I did this procedure all of the time under Leopard and there were no problems. However, in Snow leopard, the computer doesn't go to sleep anymore. The timer in minutes counts down to zero and the computer doesn't go to sleep. If I set the timer on a shorter time period (like 15 minutes), the mac will sleep. I have also tried other dashboard widgets such as Shutdown Timer and they also have the same problem.
Has anyone had this problem? Any suggestions?
