Problems with Composing in Yahoo Mail

[DeadMoney_J]

Whenever I attmept to Compose Mail with Yahoo; the screen goes white as if it's accessing the proper page and then nothing happens. I also can't Reply to any messages. This has been going on for about a week. Other than this, everything else with my Yahoo Mail seems to work appropriately. If I go to another computer though and access my account, the "Compose Mail" works perfectly fine. Thanks in advance for any help or ideas with this.
