Actually, the problem was fundamentally simple. the softeware I use to collect and/or edit images is IrfanView, a great tool. However, it had somehow been set to 75 dpi so when I pasted an image in, manipulated it for presentation, and then copied it to the clipboard for pasting into my report, it came in fuzzy. Not sure why it looked OK after pasting and bad later, but when I readjusted the DPI setting, the issue went away.
