I'm using version 10 on Windows XP

When I open to the worksheet it fills the screen but the measures and fonts are really really small. The worksheet measure cells go from 1-196 and are proportionately smaller! I don't know what the issue is. I did have to replace my hard drive but the operating system (XP) and the program itself (Version 10) are the same

Every other usage on my computer with this combination has been more standard with something closer to thirty or forty cells visible

Help me Mr Wizard
