I've been having a bit of trouble updating Calibre lately.
At some point in the install it gives me this message (and I get the smallest dialog box when I click OK):
I then have no choice but to click Cancel, at which point I get this message:
When Calibre launches, it does show it to be at the latest update, though. This started some (4 or 5; can't remember exactly) updates ago; no idea why this is happening. Any thoughts?
