upgrade to 7.2.34711.0 and all emails are blank

Help!

  • after upgrading to 7.2.34711.0, all emails in the preview pane are blank, only displaying the title.
  • double clicking to open the email in a separate window shows the same thing
  • when creating a new email, you can not place the cursor in the content area, and right clicking the content area displays no context menu.  It seems like the html control is completely missing.
