I just spent 2 hours with Yahoo! Chat - oh brother!!!!! OK, I'm beyond frustrated!!! I had them switch me back to Classic and Classic Mail works fine. I then walked through their checklists & nothing worked for the nutshell version to get their New Mail working.
I checked Flash everyday for the last 4 days. It works well everywhere else. I have used many Flash player checker sites. I am only having problems with Yahoo New Mail.
We Disabled all the add-ons in IE - no luck. Checked - Security - "Allow active content torun files on my computer" No luck.
I'll go look at the link you provided for yahoo help but at this point - I give. I do think that it is odd that it is happening in Firefox as well. After everything I have done I can't help but point to Yahoo!.
