I am using EndNote plus 1.2 on a PowerMac 6100/60.  My problem is that in
my library of about 500 references, no matter how I sort the referenced in
the display, about the last 30 or so references will not display.  So if I
have the references sorted by author and I scroll down, my reference lists
stops at around the letter "V" even though I know I have references after
that.  In fact if I do an author searce for "White", about 12 reference
come up.  

If anybody has had a similar problem and has any suggestion I would very
much appreciate it.

I also have a problem with blank reference appearing in my reference
library.  I usually have between 10 to 20 blank reference show up, always
in the '"S"s.  When I try to delete a blank reference I get error 20009. 
I have to type something in the refernce before I can delete it, but they
always reappear eventually.  

Thanks for any help you can give.
