In the internet settings menu, there is an option of Open in background - Open new windows behind the current one. It comes unchecked by default, but it doesn't seem to make any difference when I manually open new windows. Was just wondering what it actually does really. Second question is related to the stock PDF viewer. How do you delete your previous searches? I was browsing the user manual (ironically for information to question #1) and don't seem to be able to delete the key words I searched for. I already have HistoryEraser downloaded and it doesn't have an option for the PDF viewer.
