For instance, after clicking on HEAD, I see
Displaying all changes between 19e9eb6b0c81aaa80227a15357d2b9e5ba3053cc and working copy
Since that 19e9 is ancient, this diff takes ages. The only way I have found to "fix" this is to close SourceTree and reopen it. Is this a feature of sourcetree I am somehow triggering and how do I turn it off when I enable it?
If this is a bug, is it a known one that will be fixed soon? when it happens, it pretty much mandates closing SourceTree as every operation takes minutes to complete.
Note, this isn't when using shift to select multiple items. This is single clicking without modifiers pressed. Though a modifier key might have been pressed earlier but isn't anymore. Pressing and releasing mod keys (alt/ctrl/shift) does not fix it.
