When I select "VCS > Git > Pull" and initiate a pull from origin, I am shown the "Pulling changes from origin" pop-up and the waiting animation continues forever. If I click on "Cancel", I am prompted to enter my SSH Key Passphrase. After doing so, the process stops without the pull occurring.
I am using an up-to-date Windows 7 machine (two different machines, actually), and I've updated Git just to see if that was the problem.
