I'm glad that the new version works with Panther. I really missed it when I switched to Panther and had to return to my good old paper dictionaries for a few months. My old serial number didn't work however with the new version. I asked the author for a solution and he promptly sent me my new key in addition to all new serials for other software I had bought from him. I appreciated his invaluable support and would like to thank him publicly. Fariborz AMIRSHAHI - Verona - Italy
