StartX and McAfee Firewall!

[Andy]

We run McAfee personal firewall on our laptops for security outside of 
the office.  When startx is launched, the firesrvc pegs at near 90 and 
will stay there as long as it is used.  The only way to bring it down is 
by disabling the service, which we prefer not to do.  Any one have any 
ideas on how to solve this or what might be causing it.

Thanks,
Andy
