Vista - MS Office 2007 (Vista)

Any one have any ideas why my MS Office programs open up as huge and blurry? Could it be my display settings? I am at 1280X720 32bit.

This is a new Dell 530 Inspiron with Vista, that came with the MS Office 2007 loaded in it. I am trying to open some files in Excel, but it looks like it is zoomed in so far that I can't see but maybe 1/3 of the page and it is blurry. Oh and when the Excel etc is open, any other program I might have open also gets blown way out of porportion. When I zoom out to 50%, it doesn't stay.
Hope I explained this ok. It only happens in MS Office.

What am I doing wrong?

I had the same problem in reverse: On my new laptop my new Office 2007 was so tiny I couldnt read the one and only toolbar they left us. So I enlarged the screen by adjusting the DPI to about 200%. Then I could read, but it was blurry and I couldnt see the bottom of the screen to find the cancel tab. (if you do this, count how many tabs you need to get to the button to cancel so you can move the cursor with the tab key even if you cant see it). Maybe Office somehow changed your dpi. from Windows Help the following might be the answer:

If you set the DPI higher than 96, and you are running Windows Aero (the premium visual experience of Windows Vista), the text and other items on the screen might appear blurry in some programs that are not designed for high–DPI display in this version of Windows. You can avoid this issue by using Windows XP style DPI scaling for these programs.
To make text and on-screen items clearer in programs that aren't designed for high DPI
