My comment was fairly precise. Vertical scrolling with both MyCE beta styles is jerky, slow, and often freezes up completely (becomes unresponsive) - requiring closing my browser. In addition it is the worst design I have ever seen for legibility, bland, sterile, too much white space, glaring, no dividers for eye guidance, etc. None of those problems happen with the Google, V1, or V2 styles.
