Mma 2.1 and NeXTStep3.0 problems

I am using two different NeXT machines on which I just installed the  
new version of the operating system, NeXTStep 3.0 and Mathematica  
2.1.  On both machines, Mma quits unexpectedly when I am editing some  
Text cells in a notebook.  

The problem is erratic, in the sense that I cannot predict when Mma  
will quit.  However, when Mma does quit, it  has always happened when  
I have put the insertion pointer in the cell and then hit either the   
space bar (to put a blank in text), a backspace, or a comma.   The  
problem is sometimes repeatable, in the sense that when I launch Mma  
again, and I go to the same Text cell, put my insertion  bar in the  
same place, and hit the space bar, Mma sometimes quits again (but  
sometimes it does not).  Because the problem is erratic I have not  
been able to isolate the problem in a Notebook. 

I have found that if I select the text inside the Text cell, by  
highlighting it, and put it into a new Text cell, I can edit the new  
Text cell in the spot where Mma previously would quit.  This fix is  
not as good as it sounds, however, becauses it does not work to  
select all the cells in a notebook, copy them to the clipboard, and  
put them into a new notebook.  If I do this mass copying, Mma will  
still quite when I hit the space bar in some "bad" spot.  I must  
select the text in each cell and transfer it to the new cell, one  
cell at a time. Even if I do this, when I reopen the Notebook at a  
later time, Mma still quits in "bad" spots.  

I have tried to delete the .mb file before opening a Notebook and it  
does not help.

Does anyone have this problem ?
