Call to fadeIn() within a loop causing page to scroll up

Call to fadeIn() within a loop causing page to scroll up

Hi,
I am using a timer to fadeOut and fadeIn some articles such that 5 articles are displayed in rotation. However, for some reason the call to fadeIn or fadeOut is causing the page to change it's y scroll position. If I am currently at the bottom of the page, the fadeIn call causes the page to scroll up.

Is there anything obvious that I am missing?

Thanks,
Farhad
