Not really a big deal, just something I've noticed over the past few weeks. On Mac OSX 10.7.5, the Teensy Loader application gets progressively slower at uploading a sketch to a Teensy ++ 2.0 over time. Quitting and restarting the Teensy Loader application makes it speed back up, but after a few uploads it'll start getting slower again. It never causes an error, and the upload is always good, I'm just not sure why it's slowing down over time like that and figured it was worth a mention.
