UPDATE:
On the Third Party Mouse Software front......
Still looking.........
Apem Inc does not have any spec's for the DPI rate on the DT-225.
I checked some hacking, and gaming forums.
Some users reported DPI rates of 800 or less.
But I also found out that this has Dip switches in it for setting it up with Mac/PC/Sun/Some other work station.
Plus the Dip switches adjust the Baud Rate from 300 to 9600.
{I wonder if adjusting the Baud Rate would increase Pointer Speed and Acceleration enough to be acceptable for me?}
