Please provide us with further details. My sessions are working fine in IE9, firefox 6, and the EQ2 browser. I'd also invite you to run through the virus scan tips at our computer cleanup link to rule out a problem on your end. http://everquest.allakhazam.com/forum.html?forum=25&mid=130025123118577481
EQ2's in-game browser doesn't play well with Flash and we have a couple of copy-a-link buttons that use it on EQ2 pages, but that's the only thing I can think of. No reports of it ever causing crashes as a result, just those copy buttons not working. Never had a browser crash as a result of ZAM in 7.5 years (the first 4.8 of them as a user, not admin).
