http://support.microsoft.com/default...b;en-us;241652 - seems a very similar problem...
As it appears the problem was discovered in Excel, the whole thing refers to Excel in particular. But I cant see the methods for working around it in Excel differing from those for Word by very much.
It not only discusses ways to work around the problem, it also has a link to a downloadable registry repair tool to fix the problem.
Note: I started to install the fix to test to see if this also applies to Word, but as the downloadable installation was about a three-hour one I simply couldn't be bothered - I'll work around it... :bink:
