Display Word document interally

[dasymington]

With Office 2007 beta installed if I viewed an item that was an imported .doc file it showed in Word internally in UR. Since applying the Office 2007 beta 2 technical refresh, this now opens the document externally in Word. Is there any way to change this behaviour? I have .doc and .docx files included in File extensions to display in internal browser view.

I think it's probably some Office setting I need to change because if I attempt to open a .doc file in IE6 it also opens externally in Word.
