Thank you both for your sentiments, we do try.

TAD is written to look for the largest contiguous block of memory you have
and to allocate it for its primary image buffer. TAD's memory requirements
are like so:

For a color image: WIDTH x HEIGHT x 3.75 bytes                 
For a gray image:  WIDTH x HEIGHT x 1.75 bytes

TAD will always leave 1/16 of your ram available or 64K whichever is larg-
er.

ADPro (Art Department Professional coming very soon) requires:

For a color image: WIDTH x HEIGHT x 4 bytes
For a gray image:  WIDTH x HEIGHT x 2 bytes

However, ADPro allows you to specify the max size of its primary imaging
buffer. So, on a machine like an 18 megabyte A3000, you can ask ADPro to
use only enough memory as you need. 

If you liked TAD...I think you'll find ADPro better still.
