you have to remove the program with the Program manager. The new behavior is that the ext. file is stored in the prt-file so that it is not necessary to reselect the file when starting the external simulation. So just open the Program manager within CAM (not within isv) and remove the program from manager. Then you can select a new one. I think also a replace of machine will bring you up the dialog again.
Thomas is correct.
The idea is that we make the selected external program persistent inside the program manger and store it with the individual CAM setup, so that you need to select it once. If you need to change take the way as described by Thomas J.
Hope you like it.
