Description of problem

A few members - who view the site via MacBook - are reporting that the home page is displaying images in the Announcements scroller, over the top of the categories. See pic.

This started to happen approximately 2 weeks ago. It seems specific to MacBook users.

Rather than the announcement images appearing normally, ie. one at a time for the preset period, they are all appearing simultaneously, static and in a list down the page.

Any ideas would be great. Thanks in advance.

Do you mean ads, not announcements?
