Twice now, I’ve come downstairs in the morning, and found Backup open on the desktop, in a state where it looked like it was almost going to start backing up the website, but was just sitting there (not responding). This morning, I noticed that my IM client, Adium, was also not responding. I have not seen anything like this, prior to upgrading to 10.4.3, so I wonder if there may be a correlation.

Maybe I should get the combo updater and re-run it.
