sgmiller: I think I saw your ticket in our queue today, so perhaps a Support Ninja has already helped you get things sorted out. Some people report that rebooting their computer (and then re-entering it once after that) clears up the issue.
I feel impertinent for asking, but are you checking the box to have the login details remembered?

We find it rather maddening too, having so many of our customers annoyed at each major OS update and not being able to figure out why this is happening or how we can prevent it.
