Hi, I'm on Mac OS X 10.7.5 (aka Lion) and I have exactly the same problem, I click on the "i" in the upper right corner for the info pop-over and then it won't let me set the focus on the location text box or click on the compass. Both of them seem disabled for some reason, so I'm unable to use Atlas... I also recently updated from the previous evernote version through the App Store. I'm also a fairly new evernote user. I got quite frustrated just trying to find information on this, thankfully I found this thread and hopefully this will be resolved soon.
