When I reply to a message Mail does not fill in the address from the e-mail that I am replying to, does not show my various accounts to select from in the drop down menu, and does not allow me to actually type text in the message field.
When I create a new message, same thing. No accounts listed in the selection dropdown and it won't let me type in the message field.
This happened all of a sudden this evening. One minute things were working and the next they weren't.
I did a permission repair and verified the disk with Disk Utility. Not sure what else I can do safely. Any ideas would be appreciated.
