Official support answer is to use the latest version of IE / NS or opera. NS 4x is no longer supported by vB (nor are earlier versions of IE).
Theres a patch I've been putting off installing for a different issue that may fix this one however. I'll get it up ASAP, but it wont be for a week or 2 (too swamped right now with a few other projects).
We're also experiencing a flaky router issue on 1 of the backbones thats causing sporatic time outs, etc.
(Router being flacky is at 192.atm7-0.gw3.rdu1.alter.net [146.188.162.41])
Maybe a combination of the 2. Dunno.
Skwirt up your specs and I'll do some digging, also a traceroute would be good.
