I just noticed something critical in my legacy app which uses WPTools4. This was not a problem in earlier versions of my program, which was using WPTools 4.11, but now with 4.25 it seems to lose all tab stops that were contained in the footer.
For example, I had a centering tabstop to center some text between other text on the left, and text that had a right align tabstop for it, so instead of :
abc def xyz
I get
abc def xyz
And when I look at the tabstops for that footer line, they are all missing (tab chars are still there, but the line's tabstops are gone).
If load the RTF from an old copy, the footer retains the tabstops fine, so it is reading them OK... it is only when I then save it and re-read it have they gone missing.
