Comment 1 Adam Kiezun CLA 2002-01-08 11:51:51 EST 
can't reproduce
please give the class source code 
and specify what is selected when you 'paste'
do you save the file after 3) ?
Comment 2 Erich Gamma CLA 2002-01-10 08:56:40 EST 
can still reproduce.
more precise steps:
Type ttt
method m1

1) select m1 
2) copy
3) delete
4) select ttt
5) paste
->NPE
Comment 3 Adam Kiezun CLA 2002-01-14 11:40:54 EST
