Corey, To my knowledge Foxboro hasn't done this but my point was that $PICK1 or $PICK2 are variables that they created and control and they could change them. In one of the releases they changed the default color palette, (I think between version 3 and version 4), and we had to modify all of our graphics or create our own custom color palette to match the old one. The usr markers have also undergone changes in past releases. The point I'm making is that they can change their stuff to meet their needs with no warning. =20 We tried to decipher all of the magic behind $PICK1 and $PICK2 and how and when they were initialized and finally decided that it was best to create our own variables to insure that a Foxboro change in that functionality wouldn't break what we were trying to do with our generic overlays. I'm sure that there would be an uproar if they made a significant change to $PICK1 because it is so heavily used by Foxboro and users alike.

"On our generic block overlays we eliminated the use of $PICK1 and $PICK2 and created our own variables because it was impossible to predict what Foxboro was doing, (or might do in the future), with $PICK1/2 which are their dedicated variables." Tom, can you elaborate? Has Foxboro ever done anything that changed the behavior of $PICK1 after you pick something that has "=3D PICK1 CMPD:BLOCK"=20 attached to it?
