I'm having a problem regarding the  "type-writing effect" ( http://jsfiddle.net/pSUk6/6/). Once I inserted it into my site it seemed to bare an effect on my "back to top script" ( http://www.myjqueryplugins.com/jquery-plugin/backtotop) and "spry validation textarea". The spry validation comes courtesy of Dreamweaver CS6. Should I proceed and post all code here?

Anyhow what happens is that the "back to top" button shrivels in a round mole like circle and the spry validation text area dissapears when I attempt to insert text therein. When I test the site; it launches fine but after about 2 minutes; this negative domino effect happens.
