Ever since I received my new HP Ultra book with Windows 8, I was so annoyed with this. Although my ultra-book is touch friendly, it does not mean that I am putting my fingers on the screen all the time while reading a document or to scroll a page.
Especially, while reading a PDF document. Adobe Reader enables the ‘touch mode’ for all the devices as mentioned in their documentation. Personally, I am not very supportive of this decision.
Finally, I found the hidden setting to totally turn off the touch mode. What you have to do is, go to Edit – Preferences – General and change the Touch Mode from Auto-Detect to Never. There are other options as well, but this is what I did.
