Can see inbox items but cannot read or open. If I click on an inbox item a tab comes up but its blank. Sent, spam, etc boxes won't open. Delete, move, spam pop-up menus across top seem grayed-out. Actions does not seem grayed-out but none of them will open. Search goes to net not mail.

Calender fully functional.

Have I been hacked? Cannot see sent box so cannot tell if I am spamming others but friends haven't said anything. http://downrightnow.com/yahoomail site shows slowness but nothing in news. This has been going on for 36 hours now. Multiple reboots, different computer, nothing works.

Any suggestions? Should I try password recovery?
