Refactoring Disabled

Jul 10 at 2:59 PM
When trying to, e.g., rename variables, the actions within the refactor context menu are disabled. I tried this with PTVS 2.0 and 2.1 beta in Visual Studio 2013.

I do also have ReSharper installed, but I would hope that doesn't interfere with PTVS.

Anyone have a guess about what causes this?

ReSharper is to blame.

Disabling ReSharper via Tools>Options>ReSharper restores the ability to refactor Python code.
