You can not reply back how? Reply button doesn't work? Email doesn't send? You get an error? Something else?

I have the same problem, since the latest major update. I can hit 'reply' at the top of the message itself, or hit the 'reply' icon in the top toolbar, and a new e-mail box with the message below DOES open up. However its never addressed to anybody! And at that point, there's no easy way of adding an address that should have been there in the first place. I figured there was some setting to change where I could fix this design problem, but no. Unbelievable.

This is a spin off to the OTHER common problem with the update, that being when I create an e-mail or especially when I forward an e-mail, I cannot quickly raise up my personal address book and pick who I want to sent to, CC to, or BCC to. All I can do is start typing a name/e-mail or whatever, but if my address book description isn't complete and the name/e-mail aren't instantly recognizable, then nothing.

All these new design changes simply grind the process to a halt, and get people annoyed. I'm waiting for a fix to these errors.
