CHIRP

I have 6 NOAA channels programmed into the last 6 memories (121-127) on my UV-5R. Attempting to insert a row above row 125 the program hangs at a dialogue stating "moving 127 to 128". Closing the dialogue returns you to the program, but it's unstable after that, ultimately hanging after a few operations.

Terminal output:
