Squeeze Page Optin

I have a windows vista home basic. I am not sure why, but my text on my pages seem to be squeezed together and sometimes will not fit into size of format on screen, therefore, some text I cannot see because it appears cut off. And some text seems to overlap other text. What could this problem be? Pages on screen also appear squeezed smaller than usual. My screen resolution is normal so what else could it be? Please help it is driving me crazy!

I may not be exactly sure but I think it's got something to do with your actual screen itself if there's buttons on it you can adjust the size of the window.
