I have 3 computer with MS office 2007. when they open a file regardless if it is .DOC or .DOCX it will get the spinning blue circle.
the top file name display line will show the filename.docx (Compatibility Mode) then when we click in the body of the file it will show the blue circle and it will pop next to the file name Not Responding.
i installed the MS office SP3. and Compatibility update... no change
New computers i7 , 8gig ram Win 7 64 bit.
