Barbara, changing the screen resolution is the worst way to achieve this if you're using an LCD monitor. On an old CRT monitor it'd be fine, but an LCD monitor will *always* make things blurry and hard-to-read if you don't have your screen resolution set to the same resolution as the monitor - unless it's an exact multiple anyway, so 800x600 would look OK on a 1600x1200 monitor, for example, but 1200x1024 would look terrible. Even this has the disadvantage though that everything will become more "jagged", so you're better using the highest screen resolution you can and changing how large the computer makes things on that screen.

I don't know how Vista handles things, but on WinXP you go to the Display settings in the Control Panel and change the font size option on the Appearance tab from "normal" to "large" or "extra large". If you're not just having problems seeing fonts but everything else as well, you could go to the General tab and change the DPI (dots per inch) setting to "large" instead, which will magnify everything.
