This is what I would to:
* Open the Software Manager, select Adobe Reader (v10.2.276) from the list.
* Where it says "Report a Problem", tap that.
* From selection type, set it to "Other"
* Now, where it says "Tap Here To Type," paste your comments.
There is also a feature request/bug reporting thread(s) stickied at the top of this forum.
I see your point here in a text field box with a fixed width. I was only able to move the cursor in the text field using the HP TouchPad bluetooth keyboard. I suggest this also go in the feature request page.
The browser seems decent except I have not been able to figure out on how to move the cursor to the end or beginning of text. Example: If the text box I'm typing in is 20 characters long and I type 30, the beginning of the text gets scrolled and is out of sight. I normally just arrow over using my arrows keys on my keyboard or press the Home key. How is this possible on the TouchPad?
