Why would my libraries suddenly rearrange?

[Guest asrequested]

I just had all my libraries arbitrarily rearrange the order I put them in. I had to change them to the order I wanted. What would cause that?

You must have rearranged them without realizing it. Either that or some I/O problem that caused a config file to fail to be parsed and therefore reverted to defaults.

I hadn't rearranged them. Every one of them had been moved to a different position that I had never had them in. It was bizarre! Not even defaults. For instance, Live TV is defaulted to position one. That's where I like it. It was moved to position 8. They all moved to random positions. I've moved them back, and they've stayed there, but I wanted to see what the cause might be.
