Encountering a strange issue in IE 8/9 with outer glow effects. I have a modal box (created using jQuery UI) with an outer glow effect applied to it. The height of the box adjusts based on selected options, using simple show/hide JavaScript. The problem arises when the box height decreases, leaving horizontal marks or traces of the outer glow that disappear upon clicking anywhere on the screen.
It appears that when the height changes, IE fails to properly refresh the viewport for some unknown reason.
