Kathryn- Arial Unicode MS works for me. I had considered questioning the font earlier, but didn't. Certain fonts take up a tad more room than others, so experimenting may be in order.
As to the 'machine' characters you are seeing, you may wish to go to PAF 5 - Edit Individual-Options-Symbol to see if you can track down the characters you are seeing. (After you switch to a Unicode font, perhaps).
You might also paste a sample of your notes back to Word and then expose the hidden characters and commands using Word Tools-Options-Non-Printing Characters-All. You might find other tools in Word that will help in the troubleshooting.
