Hah. The usefulness of those forums will always amaze me.

I never played with UDT. At least not for such large jobs. I'll dig into that and that'll probably be my next posts topic!

A million records is something I never had to play with, too. Those X,Y coordinates are actually the coordinates of each "given-color"-pixels in many different pictures, which I'll have to compare with another smaller array (another picture).

Thanks for the feedback.
