This is a bug in OS3.9 I've been led to believe.
You can set the tooltypes and save them to get it to
remember the settings but I can't remember the syntax offhand. The problem is meant to be fixed by BoingBag 2 some people have said but I downloaded
the second boing bag from amiga.com and it didn't fix it. Maybe there is a boing bag 2 as opposed to a revised boing bag 1?
