Everything looked normal on my editing screen which is the
Design tab in RH7. Then one day, as I did a Copy/Paste onto the
screen, the fonts and images suddenly went all scratchy. But it
does not affect the output. If I do a Ctrl-W which is a preview
screen, everything looks normal. The font is normal, the images
display perfectly. And same when I generate the output. But on the
editing screen, it's awful to look at. The text is readable but
scratchy and the images are really pixelly.
I also remember this in RH5 and when I updated to RH7,
everything was working perfectly, until one day, in the middle of
the project, I did a copy/paste and it happened again.
