Hi all,

I’ve just noticed this issue(or perhaps a bug?) in firefox 1.03/1.04. When the wmode parameter in HTML is set to opaque/transparent, the hover areas in flash will be “displaced” when scrolling the whole html document.

To reproduce this issue/bug, use firefox to visit [http://mnjul.net/hoppertemp/](http://mnjul.net/hoppertemp/) when it finished loading, resize the browser window to a smaller size so that you get the vertical scroller.  
Now, scroll the page all the way down, and then half-way up. You should notice that all the button hover areas are “displaced”.

Is there any workarounds for this issue if I have to use wmode=opaque? The reason for using wmode as opaque is because I will be placing a google ad on top of the flash content.

Thanks a lot 🙂
