Project issue

Whenever I have Microsoft Project open to read mpp document, it brings the whole system operation to a crawl. Forget about using a browser whenever that program is open; it slows everything down. Any suggestions as to what causes this?

Let me guess totally outdated Microsoft suite and never heard of a Powerpoint Viewer...
Apart from updating there are good freeware solutions available too.
And now I hope the new spam filter work as expected....
