Interesting. If you know and can post the following information:
- what Internet browser you're using,
- what kind of computer it is (Mac, Windows 2000, Windows XP, Windows 2003, Windows 2008, Windows 7, Windows 8, etc.)
- possibly even your screen resolution (if you know it)
Uploading a screenshot helps too (for PC users, press Alt+PrtScrn and then save that in a graphics program).
For instance, I'm using Google Chrome (latest version), Windows 7, and a very high resolution (1440 x 900). I don't see scrollbars.
It could be certain browsers and/or screen resolutions that the scrollbars appear.
