I don't know if this works on all computers, but try holding down the CTRL key and pressing the "+". It will be blurry if you make it too big. use the "-" key to go back to original size. This is good for making text bigger if you can't see it, too. There is a thread of people's avatars- do a search. + and - are on the number pad. I just discovered this, can't believe I never knew it before...
