Finn, found the issue for the highlighting problem in Firefox 3.0. V3 added functionality to let users select multiple blocks of text on the same page by holding down the shift key. This was interfering with your slider_div on mousedown function. Changing line 215 of the js to declare return false solves the issue: slider_div.onmousedown = function () { dragstart(this);return false; };
