Lyndel - I"mjust looking to simulate the sceens, jumps, and visual items. I don't really want to "simulate" with connectivity to the extender. That's more like an actual testing of the commands which I don't mind doing with a download. The commands most always work and need little tweak. The user interface, however, requires a lot of twesking.

buzz - can you explain a little more about what/how you do your simulation? It sounds like it might work for me.

thanks all!
