I think I noticed it once.

My gf was logged into my empeg via ethernet and making LOTS of changes.
I logged in via ethernet from my computer and made a quick change and synced.
Gf hit the sync button and got very mad at me very shortly afterwards.

Needless to say... she wasn't happy and I didn't get the benefit of a doubt as to making a mistake. I just did something that was wrong and I should have known better. Ahhhh women... can't live with them, and they can't pee standing up. :)
