Mixzing Problem: Random Playback

I've got a problem and I'd like to know if anyone else has a similar issue and, hopefully, a solution.

I use Mixzing on my Rooted Nexus One, and I notice that anytime I unplug headphones from my phone, Mixzing suddenly starts playing. I could be talking on the phone, or using Beyondpod while in the car and as soon as I unplug it, the last played song from Mixzing starts blaring from the phone!
Worse still, if I take the phone out of the dock mid-conversation, whenever I end my call music starts playing even if I wasn't even listening to anything at all earlier!
Ideas, please?
