flash z-index problem

I'd like to change order flash swf and popupwindow. if the popupwindow opens . flash swf overlayed on popupwindow how can I solve this problem.

I've fou开发者_运维百科nd a solution about wmode. but some blog said wmode is so danger.

setting the wmode to opaque or transparent is your only option to get it to respect the z-order of your html. this has some drawbacks as you've noticed, but it's all a tradeoff, the other option is to rearrange your gui so this won't happen.
