I came across a rather annoying change tracking bug today: 1. New document 2. insert "word1 word2" 3. turn on change tracking 4. insert "word0 " before "word1" 5. place cursor in front of "word0" and press DEL => the char "w" in "word1" is marked INSERTED. In fact, all change tracking marks in the given paragraph are shifted on char rightwards. Same happens with backspace.
I filed this as bug 2613 (it looks familiar to bug 1827, but is not identical (bug 1827 remains fixed)). Michael, could you look after that during your ct rework of 1.5? However, I think we should also do something about 1.4. This bug muddles the whole change tracking information of a paragraph. I really lost some data before I became aware of it. Jürgen
