You should not "update" to Word 2007.
It is the worst version of Word since Word 2000.
It was marketed before it was ready.

You should at least get Word 2010 which was a good product.
Note, this is not offered or supported by Microsoft.
You need to be very careful of third-party retailers who may be selling defective or tainted versions. The best place to get an out-of-date version of Word is likely to be a local computer repair place where you can go and complain to a live person in person if it does not work.

The Ribbon User Interface takes some getting used to. Be prepared for a learning curve.

As Paul stated, this problem exists for all versions of Word.
It is unlikely that this will change.
