Wow good to know Phil that you are running a later version than 1.8.5 I was going crazy too and my notes are all sustaining with the NONPERC kits you gave me. I guess I will need to wait for the new firmware release. I will deal with the cracks and pops for now. Tahnks to BBBob for troubleshooting this with Phil. I was getting ready to video tape the same issue and send it off. BTW your purple haze is awesome.
