Yes, yet another report. (BTW: Isn't it astonishing that there are 173
frees between freeing the memory and the free memory read? Object
orientation at its best!)
I don't want you to draw your attention into the wrong direction but... If
I understand the problem correctly, some cursor becomes invalid because
the corresponding text is deleted. Now, when we look at the purify
report, we can see quite exactly where this text is deleted
(deleteEmptyPar... and related methods). Thus, I think this is also the
place where the cursor must be "corrected". Does that make sense?
(I intend to leave my office in half an hour. If you need my help, please
contact me in time)
