Hi
Congrats on fixing it! Now you see why it's so difficult to pin-down what the problem is.
Microsoft have every Tuesday as "Patch Tuesday". I think they copied the idea from Symantec (Norton) a few years ago. Symantec use Thursdays. It makes it easier and more predictable for Sys.Admins rather than being completely unpredictable. Patches and updates do sometimes break things so it's nice to know when they are going to happen. Obviously if there is a really serious threat that they develop a patch for they sometimes release it asap rather than waiting but for the most part they stick to holding patches back until the next Tuesday.
I suspect it's more to do with rebooting, or perhaps just restarting just LO after turning off the auto back-ups.
Anyway, congrats and regards from
Tom
