SourceTree version: 2.1.2.4 Windows 10
I'm not able to resize at the title bar (not getting the double arrow as I do at the bottom)
Having the same problem on Windows 7.
Also, as it seems to me to be related, I can no longer drag the window to another monitor while SourceTree is currently maximized (and this happens at least both on W7 and W8.1 on my experience).
I have the same problem. A co-worker pointed it out to me. Should we log a bug somewhere? We're also using Windows 7.
