title: Automatic outlining (collapsible sections) does not start for .ASPX files in Visual Studio 2010 SP1
body: <p>In Visual Studio 2010 SP1, automatic outlining is not enabled for ASPX files when I open them.  For each file opened, I need to click Edit / Outlining / Start automatic outlining, which is extremely annoying.  This step is not necessary when code-only (non-ASPX) files are opened.</p>
  
  <p>I use a few extensions, all of them from MS, including Power Tools, the JavaScript tools, etc., and I thought that maybe they were causing the problem, so I disabled all of them and restarted VS, but the problem still exists.</p>
  
  <p>I did not have this problem with VS2010 (no SP) on Win XP Pro, which I used for about 18 months, but I recently did a clean install of Win 7 x64, VS2010, and VS2010 SP1, and now I have this issue.</p>
  
  <p>Any ideas?</p>
