- I _wrote_ ResetADB. I'm glad to hear that someone's using it. :) I
- didn't know anything about this problem (I had a similar one with my
- Kensington TurboMouse 3 under 6.0.7 and 7.0, on my SE/30. I haven't
- had any problems of this sort under 7.0.1 or 7.1 on either the SE/30
- or my PowerBook 160, but I'll put ResetADB on the PB just in case. :)
