Do you mean the way the screen jumps up and down, Robert?
That has to do with the little news item at the top of the screen that reads, We are saddened to annouce the death on June 7 of Nancy Leeds Wynkoop, Granddaughter of Grand Duke George Mikhailovich. The text is too wide and/or deep for some screens, which forces the banner to accomodate it by expanding every time the message pops up -- hence, the "hiccup".
I have trouble with this at work, where the screen is a standard size. On my wide-screen laptop, though, there's no problem.
