alot of the times, just going into internet options and setting everything to default, and clearing the cookies and files works about 50% of the time.
This is possibly a yahoo issue. If you use yahoo thru ATT, you can call ATT for support and they will escalate any valid issues to yahoo for you.
Their phone number is 1-877-722-3755
ask for tech support at the prompt
they can remote on your computer to see if it is a java issue or whatever
if they can replicate it on their computer also, they will create a yahoo trouble ticket and give you thier member service number. Yahoo resolves 85% of these within 48 hrs.
If they cant replicate it, then they will consider it a pc issue and refer you to connect tech or to best buy's geek squad.
Personally, I would also try sending emails in safemode, If you can do it in safemode, and not in reg mode, it is definately PC related.
To get to safemode, turn your computer off and when you turn it back on, tap the F8 button until you get an advanced screen. Pick safemode with networking with the arrow keys. Log in, click yes when it tells you you're running in safemode, and then when your on your desktop, which will look alot differnt, black background with big icons, click on internet explorer and go to mail.yahoo.com and see if it works now, if it does, like i said, its pc related. If it still cant, call ATT's support if you have thier DSL or U-Verse
