Updating Microsoft Office 2007 seemed to cause a big bug in the Word application. It nearly boiled up my blood throughout the morning since after midnight.
Every time I wanted to open up a document for amendment, it started to hang. It was so urgent that I had to finally remove the MS Word 2007 application and install MS Word 2003 instead. The removal of the application took so long that I dozed off in between.
It was a draining day.
I would never do windows update for MS Office 2007 again.
