regarding jjlphoto's remark, here's some more info one potential gamma/interpolation-related problem: http://www.all-in-one.ee/~dersch/gamma/gamma.html
Is there any news about your project? Still alive?
Oh... I C - thx for the info. Not much chance for a completed project then, I guess...
You might try to PM Jonathan and see whether he's still alive or not! I wouldn't be too optimistic, though.
