Tools -> JavaScript Console:
    Error: oTxt.doScroll is not a function

The doScroll method ("Simulates a click on a scroll-bar component") appears to
be msie-proprietary dom. Use for instance element.scrollTop += 10; or the like,
that appears to work in both mozilla and ie.

As a personal note, I think it's a bad idea to not use familiar user interface
components to implement common user interface things (scrollbars for scrolling!).
