"Slow Script" Message in Safari

[Shotgun OS]

Alright, this is becoming very annoying. On these other forums I visit for a card game called Magic: The Gathering, on some threads, I get this wacked out 'Slow Script' message. Sometimes, it never gives me the message, and goes straight to the spinning beach ball of death. It gets frustrating because I have to Force Quit Safari, which closes out all other active windows I have open.
Does anyone know how to fix it, or what might be the exact problem?

I've been visiting these forums for 2 years or so, and I've never had any problems like this. I figure it is a bug in the Safari 3 Beta.

A pic of the message is attached, and a link to the thread of the last occurence is below:

In Safari 2, your link gave me a beachball for about a minute and froze Safari, but then loaded perfectly.

I just checked, and it seemed to work fine and loaded perfectly. I will probably uninstall the beta to prevent the other threads from doing this. Thanks for your help.

No worries mate. I guess that's the risk we take with beta software.
