About six months ago I installed RingGuard to prevent accidental changes to my ringer volume by accidental presses of the volume rocker. I uninstalled it about 15 minutes later, as (at that time) it prevented Locale from changing the ringer volume. I am now using Tasker, and it is unable to reliably detect changes to the ringer volume. Is it possible that something left over from RingGuard is preventing Tasker from seeing these changes? If so, how would I determine if this is what's happening?
