Can any Mac wizard shed some light on a programming problem I'm having?  My
edit record (TERec) seems to completely loose track of the number of lines of
text as I'm adding characters to the text.  In other words TERec.nLines jumps
ahead by hundreds of lines as I add characters using TEInsert.  The number of
lines that nLines jumps by doesn't seem to follow any pattern.  Line after line
of text is inserted properly and then out of the blue, nLines jumps. This seems
to occur after a carriage return ($0D) is inserted, but only infrequently. I 
also follow TEInsert with TEScroll after each ($0D) is inserted but this seems 
unrelated.  Calling TECalText fixes the edit record with nLines returning to 
normal, and all characters intact.  Is there some bug related to carriage
returns and TEInsert or TEScroll in these toolbox routines?

I would really appreciate any information as I can't find any explaination
for this behavior.
