Hi,
Thank you for posting your query on Microsoft Community.
From your issue description, I understand that scroll bar/slide bar disappears after a few seconds.
To help you resolve this issue, Could you please answer the following questions.
- On the scroll bar, you need to perhaps tell us where you are in Windows 8?
- When you have this issue; are you somewhere on the Start screen or in a Windows 8 store-style app or are you somewhere on the Desktop side?
- Where are you missing the "scroll bar”?
Please answer these questions so that I can rectify your issue as soon as possible.
first, I am on this site typing my answer to you as the scroll bar disappears on the right hand side of the screen. This happens on many sites and is very annoying as sometimes there is another site waiting in the space where the scroll bar disappeared and I am redirected to some other site I don't want.
