Sounds like dithering is your problem. It's never a good idea to dither a
bitmapped graphic. You'll always get that awful grid effect when it's
resized. Instead, capture and/or save without dithering. On HiJaak Pro, for
example, that's selectable from the "options" button when you save the
graphic. But you have to know to do it, otherwise it'll keep trying to
dither automatically and giving you trash to work with. My suggestion would
also be to lose the colors, set your screen driver for mono, capture the
image, strip the colors (convert to B&W) and then save as a color snap,
rather than a dither. It works wonderfully for me.
