+// this is a problem that has been here almost from day one and that a
+// larger userbase with differenct access patters triggers the bad
+// behaviour. (segfaults.) What I think happen is: In several places
+// we store the paragraph in the current cursor and then moves the
+// cursor. This movement of the cursor will delete paragraph at the
+// old position if it is now empty. This will make the temporary
+// pointer to the old cursor paragraph invalid and dangerous to use.
+// And is some cases this will trigger a segfault. I have marked some
+// of the cases where this happens with a warning, but I am sure there
+// are others in this file and in text2.C. There is also a note in
+// Delete() that you should read. In Delete I store the paragraph->id
+// instead of a pointer to the paragraph. I am pretty sure this faulty
+// use of temporary pointers to paragraphs that might have gotten
+// invalidated (through a cursor movement) before they are used, are
+// the cause of the strange crashes we get reported often.
+//
+// It is very tiresom to change this code, especially when it is as
+// hard to read as it is. Help to fix all the cases where this is done
+// would be greately appreciated.
