What to do to fix this error

When I visit a site I always got this message:

"a runtime error has ocurred
Do you wish to debug
Line 159
Error:'this.controlobj' is null or not an objet.

YES NO

I always say NO,so I keep seeng the page, but sometimes is appearing in the IE window. and I do the same. How can I fix this??? Thanks in advance.

 

tools, internet options, advanced tab. Make sure enable script debugging isnt checked.

 

Thanks, I did that to no avail; fix the one on the IE, but not on a specific site. Could be something else related with that specific site???

 

Sounds like it may be site related if it is just that particular site
