	Recently I put DLLists (DLList.h) in a program.  Everything was 
fine, until I went to clear a series of lists and then append to them again.
At seemingly random times, in the process of appending to a previously 
cleared lists, the program will crash with the error:

(Note... the program crashes while a list is being appended to, ONLY after
 it clears the lists.  It does not crash if I don't attempt to previously
 clear any lists with either a.clear() or a loop of a.del_after(Pix i).)

Anyone have any ideas what might be the problem here?  


Thanks!
