Windows 10 Enterprise Version 1607
SourceTree 1.9.6.1 (also affects 1.9.5.0, 1.8.3)
git repo
When I start SourceTree, it comes up in the "No staging" view.
If I change to "Split view staging", quit, and restart, it's back to "No staging".
(Is this even the right place to report bugs? Anyway, if I'm not alone, perhaps this may at least let somebody know that they aren't either.)
