Yahoo Mail new no longer works in Opera 10.10

Been using Opera 10.10 for a while now. Since yesterday, I've not been able to open Yahoo Mail new, I keep getting this message:

Sorry, the all-new Yahoo! Mail does not support your browser.
You can either download a compatible browser or proceed to Yahoo! Mail Classic.

Any idea why this has stopped working? I was able to access new Yahoo Mail just fine with Opera 10.10 before. I did a search of the forums and see others having similar problems and have tried all the usual suspects:

- Set Opera to be identified as Firefox/IE for the Yahoo mail domain
- Ensured JavaScript is selected in preferences
- Checked Browser JavaScript to ensure it's set to 2 and downloaded the latest file

I think it might be something to do with the Browser JavaScript settings as no matter how many times I set this to 2 and save, it keeps reverting back to 0 when I refresh the config page. The environment is a brand new clean install of XP with SP3 that Opera has been working perfectly with over the last month.

As of yesterday, redirections no longer working either even though I have auto redirection enabled in preferences. Has something changed in my settings without me knowing? Even the Opera forums don't work correctly, I click on a topic and it just sits there doing nothing with the progress bar at 0 kb although it doesn't freeze and other pages in other tabs load fine.

I'm actually having to type this on, Lord have mercy, Firefox which has been gobbling up all the resources as if it's trying to win first prize in a pie eating contest

Please help before I'm forced to revert back to Fatboy FireFox for good

I had the same with O10.10 WinXP SP2, check if you have all system updates - especially .NET Framework and MSXML which are responsible for Ajax
