title: VS2008 devenv not closing, keeping files from being built?
body: <p>Hey guys, have you guys run into this behavior, and if so, how have you gotten around it?</p>
  
  <p>Basically, what's happening is this: I'll have a VS2008 instance running, pop into another VS project in a new instance, and then close the new instance. After that, every once in a while VS will complain that "File  is open in another window, would you like to close it?". Clicking yes doesn't do anything; I can't open the file in the editor.</p>
  
  <p>What's infinitely worse is that, any files which would display that behavior (which maybe ones I don't know about) seem to not get built. The assembly just straight up doesn't include the classes which are displaying the issue.</p>
  
  <p>I've noticed that when I close VS there're still instances of devenv.exe running; when I kill them in Process Explorer, the issues seem to disappear, so it seems to me that they're keeping file handles open.</p>
  
  <p>I'd love to be able to trust my environment a little more than I can right now...</p>
  
  <p>Any suggestions?</p>
  
  <p>PS - I have the VimEmu installed, and that's the only plugin.</p>
