Unity freezes on play when debugging in MonoDevelop, but is fine when not debugging

When I hit play on my environment in Unity, everything works fine. However, when I close it, open MonoDevelop, and click on Debug, it opens Unity, and when I hit play there . . . it freezes. It doesn't hit any break points (not even the Awake() of any of my MonoBehaviours).

This doesn't happen on my teammate's machine (both Win 7 - 64 bit).

I'm kind of at a loss as to how to debug this. Any suggestions?

See this post from 6 months ago. Look closely at the tiny blurb at the bottom with the possible hotfix for you:
