Update Notification

I'm using the portable LO on different boxes and start them up several times a day.
I'm doing this since the start of the OO/LO long time ago, can't remember when it was.

Whenever a new regular Version comes out from the foundation the update notification jumps out, although the portable version will take some time to be updated which is quite normal.

Is there a way to turn this update notifier off? I may have overlooked something here.
