Recently I noticed a trend where some users were getting a strange black bar on the right side of their screen. Clicking in the empty space or on the scroll bar would cause weird behavior on the system and in Internet Explorer 9. So I have written a little guide on how to resolve this!
Navigate to the Tools tab.
Go down to Internet Options and click it. A new window will appear.
After choosing the Advanced Tab you will see Accelerated Graphics, this box will be unchecked. Check the box so it is no longer empty. Now you will need to close then re-open Internet Explorer.
