The same here, it's really annoying. To see this message one time is ok, but not evertime you open a document.
I've tried it but it doesn't work for me sadly...
Change your screen resolution to a higher value so that you can see the whole bar.
At the right edge of the bar there is a button where you can disable the message temporarily.
( At least until you have to restore your preferences, I think. )
