title: c# application crashes on ShowDialog() after running oledbconnection
body: <p>I have been working on a c# project that connects to a access database, but a certain sequence of events causes it to crash with a <code>AccessViolationException</code></p>
  
  <p>The issue comes after calling a database connection using oledb in a separate form than the savefiledialog, and than calling <code>savefiledialog1.ShowDialog()</code></p>
  
  <p>Note: This also applies to the open file dialog.</p>
