Tim,
I've experienced the same thing on occaision, but not on a frequent basis. You could try upgrading to the latest Netscape 4.5/4.6, that seemed to alleviate some of my lockups. So did uninstalling IE and reinstalling as browser-only, this actually resolved all my gripes. Also, when I had active desktop enabled the lockups with Microsoft pages seemed alot more prevalent. HTH
