title: OpenFileDialog always shows *.URL (Internet Shortcut files)
body: <p>My <code>OpenFileDialog</code> has one single <code>Filter</code> which is also the <code>DefaultExt</code>. I wonder why, when the dialog opens, I also get all the Internet Shortcuts listed (it is OK to get the shortcuts to folders, for instance, but not the *.URL files).</p>
  
  <p>Is there some magic switch which I can turn on in order to net get them included in the list displayed to the user?</p>
  
  <p>Currently, I have to handle the condition in the <code>FileOk</code> event handler by setting <code>e.Cancel</code> to <code>true</code> if I detect that the user selected an <code>*.URL</code> file (it is not working 100% of the time either, some shortcuts seem still to be getting through the <code>FileOk</code> filter). Not getting them in the list in the first place would be better, though.</p>
