I should have remembered this but I've never had to do it and I can't find the answer from a forum search.
What's happened is one of my 'students' has had the two T/L scroll bar areas become black. I'm hoping this might get fixed by a restore to default on startup, just couldn't find the magic trick to do this.
If this doesn't work anyone got any clues as to how to restore the missing T/L scroll bars?
