Just as a matter of interest, is your screen flat panel or CRT? Is it
connected to your graphics card by an analog or digital connection?

Do you have any experience with graphical software
like Photoshop?

My computers are full of it and have been for years.

Right now I'm running Photo Shop, Photo Paint and Nikon Capture
Editer. I've also run other stuff in the past. I'm also running Corel
Draw and Visual Cadd, both of which use vector graphics. There is
nothing like a vector-graphic circle to show up errors in the display
of aspect ratios.

So you should know very well that the dimensions of a drawn object *in
pixels* are independent of the screen display.

To the contrary. I know that in many cases they are not.

The only circumstances in which the pixels are likely to be
independent of the display is when one is using a plasma/LCD display
using a digital connection to the computer. But even then some
graphics cards can introduce errors, especially when you are not
running the screen at its native resolution.
