I know there is an existing bug for this from the Songbird days, but I can't find the status of the issue with Nightingale. Is this an issue a dev is working on? FYI I'm on Mac OS X 10.11.2 using Nightingale v18.104.22.1684 w/ mashtape v22.214.171.1244.
Thanks for the reply, and sorry to hear that, it was a great plugin. May I suggest that mashTape not be bundled with the Nightingale installer? That might prevent people like me from being confused or frustrated with trying to get it working after installing NG.
