MS Office 2010

Usually a genuine copy of Microsoft Office shows who the owner of the product is e.g 'This products is licensed to...' 2010 is still an up to date version, so there shouldn't necessarily be any reason for it to play up. Perhaps you may need to tidy up some files? Maybe it's trying to work with too much data? It's hard to be sure for certain.

If you are finding that other programs on your computer are slowing, you could always disc clean and defragment your computer using system tools.

I use Office 2010 and {touch wood!) have never had any problems.

That is so annoying annodomini
