I have Acrobat version 9 on Windows 7 and I'm having the following issues when trying to add text to my PDF:
If I use the text box, I can see the text as I'm writing, but as soon as I click outside of the text box, it disappears. I changed the text box fill and border to no color and I opened up the text box text properties and made the the text font was in red. It still doesn't work
For the typewritier, I am only able to type in red. I am not able to open up the text box text properties to edit it. In the typewriter tool box, I can only change the font size and the line spacing (no color or font).
See http://forums.adobe.com/message/4577659#4577659, message 27. You'll need to tweak the instructions as they are specfic to Acrobat X.
