I am very interested in trying the JetCam screen designer (beta version). I did a little exploration of the interface and felt that it was very intuitive and the Undo seems to be unlimited (very very useful feature). But then the bad news: loaded a pristine 1024.set screen set; screen 1 did not look right. Several LEDs appear to be on top of the buttons they are supposed to surround (like Zero X Zero Y etc.). As a test, I did nothing other than open 1024.set and then save it as Bobs1024.set. When I run Mach3 and open Bobs1024.set, screen 1 does not look right (looks like screen 1 when 1024.set was loaded into JetCam). At least that's consistent. But the Zero X button is covered by a green LED (normally should be red surround). If you click on the button, the graphics do appear. There were other things wrong, but I want to keep this simple.
So, I am excited by the potential of this screen designer and very much want to use it, but it appears broken right out of the box.
