Rob,
Don't anyone get me wrong... I love 99SE.   I just don't understand why a
simple task like load the netlist in takes so long on a clean (large)
design.  Medium size designs are fine.  As I have mentioned in past
responses, I clear the old netlist first. Then reload a fresh one.   It is
quick and faster than any other method, I have seen. but large designs choke
big time even on a clear slate.  This may be one of my last complaints about
this Program, otherwise I fly thu a design without a hic-up.    But thanks
to ROB and IAN I know I am not alone, I guess that made me feel better.
