All I know is that it is a DROID x and I just did an update today.
That seems to be a DROID specific problem, as I've got one of the older models (Original DROID) and it does this as well from time to time, among other interesting little quirks. It's just part of the way the DROID software works I guess, I don't know a way around it other than rebooting the phone though.
