SmartSDR 1.12.1 problems

Hello all, The software was adding a second slice to 222. When I deleted the second slice, the radio crashed. I had to cycle the radio to get it back and it continued to add the second slice. It also did not work properly on 50 MHz transverter. So I reset the radio and reprogrammed all of my 10 transverters. Worked great. After about 3 weeks it started again with adding a second slice to 50 MHz transverter. When I deleted the second slice, the radio crashed again. Is the software bad?

Thanks, Paul WA3GFZ
