Can't write emails. Can click on write and a blank email comes up but can't tab to enter send to info, subject, or text of email. And can't edit text or anything. I can click on "To" to send but can't get from there. Also, I can read emails I receive and click reply or forward and the new page comes up but I can't enter info and tab down to anything. This has never happened before and it has been several days now. I try restarting but the same situation remains. I've checked all my preferences and nothing is out of the orinary. Please help. I'm getting desperate. One strange thing is that after I get an email to send to if I hit tab and just write a text in without seeing anything and then hit send the message will send with whatever I wrote in. I can go to my sned folder and see the message I send even though nothing appears on the email I am apparently writing so I can't see what I write , correct the text, delete and revise.
