Whenever I use facebook on my lap top, the lower left hand corner says error on page. How do I fix this?

[Julie]

Everytime I use facebook on my lap top, it says error on page in the lower left hand corner. When I use facebook on my desktop I have no problems. I can't write on friends walls or accept requests, because the buttons don't work. It used to work on my lap top, but now it hasn't worked for a few weeks. I've tried running virus scans, clearing my temporary internet files, updating Java and downloading IEfix.zip. It might be an error with javascript, however I don't know how to update it or see if it is working correctly on my computer. Since this has been ocurring for a few weeks, I've ruled out the possibility of it just being an error on the website. What's going on??? Help would be greatly appreciated.
