On your question #3, I had PAF3 before I installed PAF4 and the TOOLS/PREFERENCES/FOLDERS didn't change from PAF3. Now that I have PAF5, it still points to PAF3. It looks as though when you upgrade, that part stays the same. Doesn't make sense, does it?
Have you had any trouble printing reports? I can't get any reports or lists to print at all since I installed PAF5!!! I keep getting errors that the printable area isn't correct and to adjust the margins, but no matter how I set the margins, I get the same error. If you're able to print reports, maybe I should try downloading and installing again. Please let me know as soon as you can as I have converted my file to PAF5 and PAF4 will no longer open the file.
