This brings back to mind an FPW 2.6 app which at the time had been running in WIN 31. The user upgraded to WIN 95 and the app ran OK but objects in the form were sized relative to each other. There had been no change to the app between OS changes. The key here is that objects were differet WITHIN the form. I.E. windows treated font metrics differently between OS's.

You may have a situation which you cannot control. At least, I never got a proper answer from MS on mine.

Also keep in mind that font metrics are not quite the same on paper as they are on screen so the wrap may not occur exactly at the same place.
