any1 have this. stays on til i take battery out. opened it up once 2wks ago to try and find perhaps a loose wire etc, didnt find much, small pebble fell out and i thought that was it b/c the switch worked again. but i came home from this wk's race and i heard my radio beep when i sat it on the bench in its bag. on again. any1. love this thing and i want it fixed. even if my m11 finally gets pressed into the #1 slot and m8 down to the backup. thx for help
