Scroll bugfix

Hi Roberto,
This is the fix for the scroll issue. With this, if the vertical scroll bar is not at the top, then changes in the views go well, else things get distorted. Note: we have included a few variables that are skin-dependent, these are:
var initialOffset = 40;
var elementOffset = 30;
Maybe it would make sense to put the skin dependent elements all together somewhere. I assume you are the best one to make that decision.
Thank you!
 Julio
