I have a transparent Flash movie that uses z-index and absolute positioning and is wmode=transparent because the SWF which is 300x274 has a visible area of 300x100 until rollover when it appears to expand over content until rolloff.
In Safari & FF for the Mac the expandable area of the SWF, even when it’s not expanded on rollover prevents clicks on the links, and there is no cursor.
If it matters the links affected are popups that use <a href=’#’ onclick=‘window.open … ;return false;’>
