I recently reformatted and installed Windows XP Home fresh on both my desktop and laptop. All worked fine even after getting updated until the last update on each. On the desktop it included Service pack 2 update but not on the laptop, it was a new update but still has only service pack 1. On each computer the browsers both IE6 and foxfire started running very slow. IT would take many seconds to get new pages open. On the laptop I restored and IE6 works fine but I am still having a problem with Foxfire and it also received a Foxfire update. Any idea how to fix this problem without restoring and losing the needed update? I have run XP on both systems for a good while and never had this problem.
My desktop is 1.3 gig with 512 meg of memory and the laptop is anToshiba 850 Mhz with 512 meg of memory.
