Lieber Stefan,
Thank you very much for your reply yesterday. My software version is 2018.2c Premium. I wish I knew how I managed to corupt this Index Card GUI, but now it is again visible in the Tour Automatic Editor.
Firstly I activated repair from the WinDigipet USB software stick:- no change. I then reloaded the backup software from three days ago:- again no change. Then once again from a different location stored four days ago:- BINGO, it has reappeared!!!
