I just had Adobe Acrobat Pro DC 2015.06.30033 installed and tried to sign a document. My Profile opened up on the right side of my window when the Fill & Sign button opened the top menu, so I tried to enter my missing address. Most of my typing worked fine, but whenever I typed "a", it opened a message window to Add or Edit Form Fields and then went to Prepare Form, from which I had to escape manually. Back in My Profile, whenever I typed "c", it just closed the Fill & Sign menus. Back in My Profile again, whenever I typed "t", it opened the Edit PDF menus. I tried the rest of the alphabet without any similar problems. I was eventually able to enter my full address by cutting and pasting those three letters from other sources.
