Android Keyboard, arrow key not scrolling page in browser

[Aurolex]

Hi guys, I just got my S2 the other day along with the samsung keyboard and case. Everything was working fine with the keyboard until I got home today and turned it on and now the arrow keys no longer work to scroll the page up/down in the chrome browser. The space bar works fine to scroll down quickly but all of a sudden the arrows stopped working in the browser. I tried resyncing the keyboard and turning the tablet on and off. The arrow keys work fine in other areas of the tablet such as moving across icons on the home screen and app drawer. Not sure if I changed a setting somewhere and lost the pg up, pg dn functionality. What am I doing wrong? Thanks
