" I just could not get my head round how to co-ordinate what I was seeing with trackpad movements."

I also tried the trick on my powerbook. I thought it would be easy to adjust to using the trackpad differently. Nope. Very difficult.

Nice to know that this option exists, although I doubt I will use it much, if ever.

I guess I need to upgrade to some new hardware. I can't get this to work on my TiBook G4 (400 MHz), nor my PMG4 DP 450.
