This is a demonstration of the bug happened on 5 conditions:
Object aligned to the right or to the center, but not to the left (align=right OR center) - OR - have some text/object above the flash, (In this sample, we both right-aligned and have this text above the flash)
Zoomed (style='zoom:40%' or any other value)
Using SWFObject
Flash's "wmode" parameter must be "opaque" or "transparent" but not "window" (or omitted which is the same as ommited)
You must use IE6 or IE7 (maybe IE5 also, never tried, however not Firefox or non IE browsers)
Ready? click "With Zoom" link below and the flash will disappear!!!!
