Hello,

I don't know if this is a real bug, but I found a strange behaviour.
I have a jQuery Menu block in a sidebar which is a div with CSS property 'overflow-x: hidden'.
No elements are overflowing the div, but a vertical scrollbar appear at the right of the div.
If I remove the overflow-x rule, the scrollbar disappear.

I don't know why but the problem seems to be fixed by adding the following CSS rule to my custom theme's stylesheet:

ul.jquerymenu li.parent span.closed:after,
ul.jquerymenu li.parent span.open:after {
content: ".";
}

In jquerymenu.css the rule looks like this

ul.jquerymenu li.parent span.closed:after {
content: "Expandible menu item";
visibility: hidden;
}

Note: I'm using Firefox 18.0.1
