Sounds like you just ned to change the resolution on laptop. I'd try 800 X 600 to start. Right click on desktop and go to settings. You'll see tab for screen size.
My son's Dell Laptop had to have its HD re-formatted and reloaded with his W98 SE CD. After installing his W98SE all screens are "shrunk" but appear perfect except for the reduced size. I went into "Control> Display" but I don't see any settings that I could use to expand the screen. Any suggestions???
