Under View controls, I configured my trackIR 5 to allow me to zoom in and out. It works except for a very important detail. There is no progressive zoom in or out. If I move a little forward it zooms completely in, if I sit at the back, it zooms out completely. There is no middle point, it is either in or out.
I have verified through my track ir manager program that it was not problem with the unit or the drivers and no, it zooms in and out smoothly and progressively as expected.
