Word 2003: Save As Freezing

Microsoft Office Word

When I try to save a Word document using Save As, Word freezes if I save the 
document any place other than in My Documents.  For example, if I use the 
pull down menu in Save As to go to the C drive, Word freezes.  Essentially, 
the pull down menu in Save As freezes Word 2003 every time.  Suggestions?
