I'm blind!!

I am trying to track down a 10 pixel problem on a web page in IE 6. So I set my monitor to 800x600 to see if I found it or not (not).

And hoo-boy. I am not completely blinded by the zoomed in graphics. This is a Dell 19 inch flat panel. I just measured, and the letter "I" on this form is 6 cm tall.

It could be worse... my dad's computer is a 21 inch set at 600x400 with Large Fonts turned on.
