Often, SourceTree gets into a weird state whereby none of my modified files are shown. In other words, going to File Status tab and refreshing doesn't show anything, despite command line git status clearly showing something was changed.

I then try to get the Uncommitted Changes commit in the Log / History tab to refresh.. and when I refresh that view, it blocks in the Loading... state forever:

The repositories this happens on are both big and small. It happens a lot, usually when I have several repo tabs open. However, lately I've been working on a smaller repository (113 files over 32 folders taking ~4.5MB of diskspace). So I'm thinking there is a more critical problem here.

And once SourceTree is in this state, the other opened tabs behave the same way; ditto on even opening a new repository tab (so opening/closing the tab won't work).

This happens frequently and the only fix it to close/restart SourceTree.. and then do the same again later when it gets into the same state.
