Javascript Enabling?

[LadyBird]

I can't access my emails because it says I haven't got javascript enabled, this problem has only happened today, normally I don't have a problem (yahoo beta).
I know that I can use the classic version of Yahoo mail to access my emails but it's a nuisance.
I have checked the security settings in Internet Options, Scripting and it says that Javascript IS enabled, not sure what to do next. Would appreciate any advice.
I'm using IE 6.

It seems you are using new yahoo mail, which needs latest browsers.For error free emailing use yahoo mail classic

Use the below link to return to yahoo mail classic and click yes ,when it asks for "opt out"
