I'm having a problem with the Captify plugin, and I need help resolving it.  

The plug in works fine other browsers. but I get an error message with IE8 (haven't yet tried it with IE7 or IE6).  

The error message tells me that there is an error in the jquery file, but from what I've heard from others, this is not necessarily to be trusted.  It says:

Message: Invalid argument.

Line: 4618

Char: 4

Code: 0

URI: file path...../jquery.js

I'm starting out with javascript and I know nowhere near enough about it to be able to even try and fix this on my own.  Can someone help?

Thanks,

Rachael
