Have found this bug has gone from irritating to distracting. It is giving me the false impression that there is an error to be resolved, and the more effort I put into trying to ignore this the more likely I am going to start ignoring important flags.
This false alert that is "crying 'wolf'" needs fixing.
(PS I'm also on Windows, not Mac)
I have cross-reported this onto the Windows issues list: SRCTREEWIN-10820
All, We are unable to reproduce the issue in Mac and assume the issue is for Windows version of SourceTree. Kindly let us know if the issue persist in Mac. Also please share the detailed steps to reproduce the issue.
In the meantime, We request you to kindly install/update the latest version of Mac i.e. 4.2.3 and test.
