[jQuery] Interface: Slight problem with slider

[jQuery] Interface: Slight problem with slider


I am experimenting with the slider functionality of te interface
plugin. H have managed to get a workign slider, but I noticed a
slight but very annoying problem in FireFox 1.5. When I select and
drag the handle around, it seems to jump down and to the right by one
pixel. Has anyone run into this problem?
demo code:
div.slider {
    width: 200px;
    height: 15px;
    position: relative;
    background-color: #CCCCCC;
    border: solid 1px black;
    margin: 2px;
    padding: 0px;
}
div.slideHandle {
    width: 5px;
    height: 15px;
    position: absolute;
    background-color: #000000;
}
$('#test').Slider (
{
    accept        : '.slideHandle',
    restricted    : true,
    onChange    : function (a,b,c,d) {console.log (a + ', ' + b)}
});
<div class="slider" id="test"><div class="slideHandle" id="slideLow"></
div></div>
