 163 // we store the paragraph in the current cursor and then moves the
 164 // cursor. This movement of the cursor will delete paragraph at the
 165 // old position if it is now empty. This will make the temporary
 166 // pointer to the old cursor paragraph invalid and dangerous to use.
 167 // And is some cases this will trigger a segfault. I have marked some
 168 // of the cases where this happens with a warning, but I am sure there
 169 // are others in this file and in text2.C. There is also a note in
 170 // Delete() that you should read. In Delete I store the paragraph->id
 171 // instead of a pointer to the paragraph. I am pretty sure this faulty
 172 // use of temporary pointers to paragraphs that might have gotten
 173 // invalidated (through a cursor movement) before they are used, are
 174 // the cause of the strange crashes we get reported often.
 175 //
 176 // It is very tiresom to change this code, especially when it is as
