So the"commit" button on my source tree seems to most of the time be unresponsive, I can stage all my files, but when I press commit, nothing happens.
Also, the "Push changes immediately" checkbox is greyed out.
I can resolve this issue usually by closing and opening SourceTree, but the problem usually comes back after about 5 - 10 minutes.
I'm on Windows 7 using version 1.9.10
