I think this may be a duplicate of #98. Still I have updated to version 2.1.0 but the tests are still failing in a dual monitor setup where the main monitor is to the right.

I have created a Junit test that runs when the main monitor is to the left and fails when the main monitor is to the right: https://gist.github.com/gorbeia/60e7c6039cd2e8592243.
