title: VS 2010: Why the "Autos" window items appear\disappear in their visibility area?
body: <p>Windows 7 x64; MS Visual Studio 2010 SP1.</p>
  
  <p>I press the F10 key step by step into DEBUG mode, and look the "Autos" window items. I see some variables (in the "Autos" window) sometime appears/disappears in their visibility area (and they are already initialized). Why it happen? Look the screens below.</p>
