Viewing file diffs in staging areas is unreliable

Viewing of the individual file(s) in either staging area can prove VERY frustrating...

Without warning or any specific set of circumstances the following can happen:

• Clicking on file FOO.txt in the "Staged files" area will sometimes show the diff of file FOO.txt in the "Unstaged files" area (The opposite scenario also occurs)
• Clicking on file FOO.txt in either staging area will sometimes ALSO show BAR.txt or INSTEAD show BAR.txt
• In Unstaged file diff area, selecting multiple lines and pressing [Stage selected] or pressing [Stage hunk] will sometimes bring you to the Staged version of that file, leaving you to question whether the staging even worked properly (The opposite scenario also occurs)
• In Unstaged file diff area, selecting multiple lines and pressing [Stage selected] or pressing [Stage hunk] will sometimes not do anything at all, pressing the stage button again will throw a git error saying something about not finding the lines in question (which means it was properly staged the first click, but not updated) (The opposite scenario also occurs)
• etc...

This is one of many many issues introduced in 2.x, Please do better testing before releasing new versions, it seems with each update that 1 bug is fixed and 5 more are added. For the last few years I have been using source tree it has been going consistently downhill.
