Pressing the print screen button and then alt tabbing to MS Paint works. You can paste it there and save it as a Jpeg or PNG. Hope that helps a bit.

I think I've seen this before. I don't remember if there was a fix, but one possibility is that your graphics control panel is trying to force AA or AF filtering. I've run into this on other games when that happens. Another possibility is that the graphics chipset itself might be a little too old to run it. If you have access to another PC, you can try running it on that to see if the error persists. - I'm glad you were able to figure out the image uploading. It's a useful thing to know how to do in general, and it really helps us out. ;-)

Hope some of that helps,

-Cheers
