When I had my 02 a couple of years ago I did the same thing. Disabled the touch scroller then re-enabled it. It never worked again until I sent it back to OQO for repair. I could never figure out why it broke when disabling it.
Since OQO is out of business that is impossible.
I will just keep on fiddling hoping that it would work again.
SO DO NOT DISABLE TOUCSCROLLERS! THEY WILL NEVER RE-ENABLE! At least don't risk it.
