Javascript problem with wordpress 2.51

< script language="JavaScript" src="https://searchirc.com/jscript/ircsuper_top5.js">< /script >

I am trying to add this script to a post in wordpress. On one computer (windows vista), I am able to add this script successfully and hit save button perfect fine and everything looks good.

But on another computer (windows xp), when I add this script either to the post or to the custom field and hit save or add button, it just tries to load forever and eventually results in page takes too long to respond error.

I have to mention that I am using firefox on both computers. I have also tried IE on both computers and its the same, works perfectly on computer 1 and not on computer 2.

Been trying this for past two days downloading all kinds of different plugins that will allow javascript to be posted into wordpress posts without any luck ?? Any suggestions please?
