I think the only thing we could do to help here is to switch off the scrolling banners altogether.

But if things are changing for you, when nobody has made any coding changes to the site banners, then it kind of suggests a problem with your computer. Not that fault can be totally assigned one way or t'other when there is a communication issue, but you know what I mean.

The trouble is that I can't replicate the problem, which it makes it almost impossible to do any meaningful tinkering with the code.

Anyway, when I've got some spare time, I'll try to have a look at some other options to replace or rework the scrolling banners.
