Thanks Frenchy!

Michael, been working on this for awhile now, and things do work BUT it's amazing how SLOW the Randomize routine is. Is there anyway to speed it up? I tried it on my i5 Mac Mini and it was slow, so I took it to my monster 16-core HotRod PC thinking it would speed things up, but the Randomize routine is as slow there as on the Mac.

A grid of 100 x 60 boxes takes a good 60 minutes plus to randomize. Perhaps the redraw is the problem? If so, can we get an option to turn it off?

I'll post some images soon-- and if time permits a video tutorial.

Thanks again!!!
