Mike- Even if you have previous semi-satisfactory experience with chart printing from UFT, that was never UFT's long suit. But one thing you can try is to use Windows explorer to go into the UFT directory and delete any old boxchart files that you may have created with a former printer.
Then pick up any version of FTM from 5.0 or later at a flea market and gedcom your data over there for Win 98 chart printing. Or wait intil you upgrade to Win XP and TMG gets the bugs ironed out of TMG 6 and do your charting that application. Good luck, John
