title: Visual Studio 2010 does not reload open files
body: <p>Prior to today, if I quit VS2010 and reopened it, my previously opened solution was loaded and any previously opened files were reloaded and displayed in their correct positions.</p>
  
  <p>Now however, the solution is reopened but no files are reloaded. All the files I had open are closed.</p>
  
  <p>I didn't change any settings or do anything specific to stop this behavior. Looking through the options dialog panels, I do not see anything that applies to this behavior.</p>
  
  <p>What gives?</p>
