I've been having this problem for a few weeks now in 6.0.1. I'm concerned
about my system not being up to date.
Attached is an image of the update manager. The screenshot program actually
failed to capture one detail accurately: the curser in reality is the round
spinning curser, not the white arrow as shown in the image. I don't know why
the screenshot program doesn't reproduce this faithfully.
For anyone interested in this problem, there's also a bug report:
