Clipboard works great now, but after installing the latest (0.37.5) version for the first time on my home iMac there are now 4 my.1999.io app windows open. I'm pretty sure I didn't do that. See screenshot here.
Each of the 4 windows are showing my blog on my.1999.io but one of them has an empty dialog open titled "Hoisted message". Also, in Safari there are 2 new tabs open. The first is at http://localhost:1401/?oauth_token=13439-2WHetc... and says "Welcome to the camp!". The other is at file:///Applications/1999.app/Contents/Resources/app/index.html and shows what looks like an unauthenticated view of the blog ("Please sign in to twitter, etc....").
