Sometimes the program will become extremely unresponsive 
and use 100% of my CPU.  Strangely, this only seems to 
happen when the program is idling on the first screen that 
you see when you start it up.  What could be the reasons 
for this?
Also, the program is likely to freeze up when I try to 
update a large site and it scans through all of the files 
that I already have available on my HD.  Is this a problem 
with the program or just one of those unexplainable PC 
issues?
