Word 2010 opens documents very slow

Lately my WORD  documents opens very slow. I created a hello world document and  saved it to disk. When opening the document it took about 60 seconds to open.

I seems that the normal.dot template file was the cause of the trouble. 

The solution is:

Open File > Options > Add-Ins > Manage > Templates > go > attach Normal.dotm > OK

and WORD is blasting fast again!
