When Word is opened and I click on the font selection button (default is
Times New Roman) Word freezes. Every time. How do I fix this?

Anyone knows the difference between Arial and ArialMT?
Thanks in advance

Using Word 2007, several secretaries in our office print garbage instead of
the address when they use the Envelope feature.  Seems to happen when the
font is either Cambria or Calibri.  Using HP Laserjet printers with the
newest print drivers.  Can you help with some solution?  ...
