All my browsers suddenly don't support Javascript files anymore?
I am facing some weird problem on Windows 7. JavaScript suddenly stopped working on windows 7 on all browsers. All browsers have JavaScript enabled. I have three browsers installed IE 9 Beta, Google chrome, Firefox 3.6,
I tried disabling and enabling JavaScript again but problem persists.
How can I diagnose and correct it ?
Thanks for any help

Problem does not occure only for this website but also for Gmail in which text messaging does not work ...
