I downloaded the zip file and i get the green and white Darwin PSK icon on my desktop. When I click on it the same type of icon will bounc in my dock but then be gone. It is just like the program tries to open but closes. I have the latest version of Jaguar, not Panther. I hope this isn't the problem. I guess my issue is the same as Kim's, KC9BZL. Can anyone help me get this software running please? Rem K6bbq
