title: Visual Studio 2010 hangs up when opening a .sql file
body: <p>I launch VS 2010, and simply open any ordinary (or blank) .sql file and it shows up incorrectly drawn inside the IDE.  It draws the document tab, but nothing else.  If I type on the keyboard, VS locks up.  This only appears to be a problem with files that have the extension ".sql" and has no bearing on the actual content. I also noticed that in the Solution Explorer, those .sql files show the icon that is the same one associated with .js files.</p>
