The ACE12 Utility
=================

Though absolute positioning is not new, the ACECAT III 5"x5" Graphics
Tablet represents such a dramatic breakthrough that some applications do
not yet support its 5"x5" parameters. As a result, after installing for
some  MM1202  compatible applications,  the  tablet's active area may
correctpond to an area that is slightly smaller than your whole screen.
This problem occurs with applications that are designed to work only with a
12"x12" tablet. Provided on your Drivers/Utilities diskette is a utility
designed to correct this problem. ACE12.COM remaps the 12"x12" parameters
requested by your DOS applications to match the 5"x5" active area of your
ACECAT III.

This utility is required only if you plan on running programs that
recognize only a 12"x12" tablet format.
