ShiftIt is not resizing/repositioning any apps (i.e. it's not working)

[mnovakovic]

I couldn't think of a better title - the app is active but it doesn't seem to be resizing any windows. None of the keyboard shortcuts are working and if I manually press an action in the app pop-up menu nothing happens.

I tried restarting it of course, even a few times.

This happens occasionally, sometimes the resizing works for only a few apps, but sometimes for none.

I'm on the latest version of ShiftIt. Also, I am on macOS Sierra, version 10.12.3.

Please let me know if this is a known issue and there is a known solution to it. Also, please let me know if I can provide more debug info.
