While working on the test-paper composition system today, I ran into a problem: FLASH was covering the floating layer. No matter what I did, it always rendered on top and simply could not coexist with the layer. So I went searching, and finally found a good fix: the key parameter that keeps Flash from blocking floating objects or layers is wmode=opaque. How to do it: for IE, add the parameter inside ; for FF, add the parameter wmode=”opaque” inside .
