I tried an older version of Opera and got a similar failure rate.
What's weird is that the error message (which pops up in a dialog box) says that it can't connect to adserv.talkzilla.com
Why is that weird? Because there are no references to adserv.talkzilla.com in the page. The adserver is now adserv.stocksite.com and that's what I see when I do a View Source.
I'm never seeing any kind of problem when using IE, though. My guess is that your IE is a bit on the old side?
Nope, now I'm getting it in IE and I think I know exactly why. brb
