Backup utility won't close
Lately, when I try to Backup my files using the Backup utility, the archive won't close at the end of the process. It gets stuck there, and I end up having to Force Quit to even shut down the computer. It happens with all the plans. I've attached a screen shot. It is stuck closing the backup for my Personal Data & Settings. How do I fix this issue? Thanks.
