title: Visual Studio Unit Test Sessions window automatically popping up whenever I open my solution
body: <p>And I don't want it to. What gives? Is there a setting to disable this thing? Basically, I accidentally ran the built-in test runner instead of my preferred (resharper/ncrunch/etc.) test runner, and now this blasted window pops up every time!</p>
  
  <p>Note: Not the same problem as this question: <a href="https://stackoverflow.com/questions/3671351/how-to-keep-the-design-window-from-automatically-popping-up-in-visual-studio-201">How to keep the design window from automatically popping up in Visual Studio 2010?</a></p>
