Which browser are you using? If it's IE try reducing the magnification via the magnifing glass bottom right of the browser page. It's more likely that your resolution settings are set too low. Right-click on your desktop and choose Properties > Settings button and move the slider up a little, have it at least 1024 * 768, it really depends on the size of your screen, but experiment to get it right.
I changed the settings from 1024 x 768 to 800 x 600, it wouldnt slide along so it was one thing or the other, anyway the page fits the monitor now although i had to reduce the text size to smallest but its still too big !! cheers P M
