I've implemented the jquery.combobox plugin (http:// jquery.sanchezsalvador.com/page/jquerycombobox.aspx) on a site (http:// www.powerbuy.com.au). The problem is that when you click on the styled comboboxes in IE, the page "jumps" down, and sometimes this pushes the combobox off screen. I know this plugin relies on the dimensions plugin, and both the jquery and dimensions plugins are the most recent version.
I think this problem has something to do with the celculation of the size of the view port (as the amount this jumps seems to be related to the size of the viewport,with smaller viewports causing this to jump further). Any help would be greatly appreciated.
