Might have been.  I love that thing.  Regarding the one for the Leigh jig, I bought the D4 back around 2000.  I hated using it because it made such a mess.

Fast forward to when I got the PC version.  I kept intending to order the one for the Leigh, but never got around to it.  Then one day I was in the back room at Woodcraft talking to the owner and looked over and saw a bunch of Leigh boxes on a shelf, and the one for the D4 was among them.  I took it home that day.

Funny, I asked him why that stuff wasn't out front and he said it just takes up space and doesn't sell.  He said later he wound up dumping that remaining stuff on eBay.
