XP Home SP2, 2.24Ghz Pentium 4, 1GB RAM: since installing IE7, I have periods where everything on the pc seems to lock up (a la the Win 95 days). It eventually clears up, but only after some time. I've found that if I immediately bring up the Task Manager and then close it, the lockup ceases. Has anyone else experienced this? Joe Titone tertia at earthlink.net
