If you are exporting your reports in Rich Text Format (RTF) as used by PAF 4.04.18and (presumably) later versions, you may have problems opening and printing in certain Text Editor programs other than MSWord. "Double Printing" may be unhidden "hidden text". You may also be inadvertently introducing bad RTF commands by using characters such as curly braces and backslashes..
If you want to do some heavy duty troubleshooting, the RTF standard can be downloaded from the Microsoft site. Open the standard in Wordpad or MSWord, not Wordperfect.
