Thanks for the clear instructions.  I can reproduce the Lisp errors, but 
so far I haven't seen an abort.  I've had one session running for about 
24 hours.

I'll look into the Lisp errors when I get a chance, but I wonder if 
there's something else going on (BLODA?) that's causing the abort on 
your system.  Do you have access to a Windows computer that doesn't have 
Symantec Endpoint Protection installed?

By the way, there have been some recent changes in the way emacs handles 
the blinking cursor.  One of the changes turns off the timer for the 
blinking cursor when emacs is idle, so it's possible that the problem is 
already fixed in the emacs trunk.  I'll look into this also.

Ken
