I switched to IE for the same reasons (well... that and the instability of Netscape 6 and my own lack of patience for them to fix it). I never used NS 4.7 for any amount of time with Win2k to be able to see it hang like it did in Win98. In the past few months, I've been seeing the same hanging in IE, though. Not nearly as bad as I did in NS, but it's still there. I'm wondering if this might be a cache size issue or an issue with a HD being close to full. I know drives slow down considerably when they're getting full.
