It will probably fix the problem if you clear your browser's cache. Close the mail page, click Start > Control Panel > Internet Options (or on Internet Explorer toolbar click Tools > Internet Options) and delete Cookies, Temporary Internet Files, and History. You might also click Start > All Programs > Accessories > System Tools > Disk Cleanup > and run Disk Cleanup.

You can also use this link to check and send your Yahoo! Mail, although it doesn't have all the features of the regular Yahoo! Mail site. http://us.m.yahoo.com/p/mail?7=C&tsrc=rawfront
