Yahoo mail not working right


New Email
I pull up my yahoo mail and I can read my mail, but I cannot delete it, alone or with other emails that need to be deleted. Also, I cannot seem to reply to an email without writing a new email to that person. Basically, all I seem to be able to do is read my mail. I haven't been able to open my folders on the left side, delete, reply, or even go into my inbox without using the large X in the upper right side. This just started today. Thanks for any help.
