I'm having this exact same issue. I'm actually at a pre-purchase point in evaluating this software.
I love how breakaway handles the audio. I hate that it's so user vicious when it comes to living in the same environment as Teamspeak.
I've already yanked the plugin off my computer after having it less than a week on my machine b/c I needed to use Teamspeak when I was needing to use it. The breakaway plugin so far is seeming to be more of a "luxury" software that I just can live without. I'm almost tempted to buy it if and only if I can install and uninstall it without making the program flip out and lockup.
Jesse G would you be able to do a series of images to show what you mean and how to fix this?
