I have noticed that when the CodeRush Options window is open, VS2017 no longer appears in the task switcher panel (when using Alt+Tab).
In VS2017, click CodeRush, then Options.
The VS2017 is not visible in the 'list'.
Win+Tab works as expected.
A very minor issue, but noticeable since i'm trying to match my VS2012 CR settings.
VS2012 with the non-Roslyn CR works as expected
