Regarding scroll bars...

Each OS (and browser) treats scroll bars differently. For example, Mac OS has a system setting that allows you to control if scroll bars are hidden or visible on the page. In addition to OS system settings, each browser displays scroll bars a little bit different. Some have transparent bars that fade away when you're done scrolling and others have old-school blue and bulky scroll bars at all times (sexy, right?...not so much).

Please keep in mind: scroll bars are a system-controlled element, not a theme-controlled element. Currently only one browser (Chrome) allows CSS to control some elements of the scroll bar design, but this option is currently very limited. There are some popular approaches that hide the scroll bars and utilize JavaScript to add 100% custom scroll bars, but this approach is VERY buggy and causes issues on most mobile devices.

If you think your site has issues, please provide the details of both the OS and web browser that you're using and I'll be sure to check it out for issues. As always, please be sure to compare the performance of your site against the demo site for reference: http://themes.themolitor.com/vysual
