Layering not working in HTML Publish

Hi everyone reading here!

I have created a simulation in Captivate with a play bar at the bottom. The play bar is transparent. I have published it to a SWF file.

In Lectora, I have a menu button which is in line with the SWF's play bar. When I publish my course to HTML, the SWF animation is always on top, therefore hiding my menu button. I have tried the following.

- Set the menu button's layering to front.

- Set the animation's layering to back.

Above did not work.

- I have selected the tick box for always on top of the menu button.

Did not help.

- I have created the menu button with a transparent background, then the background appears to be white in Lectora.

Will the animation always be on top? Regardless of the layering settings once you publish it?

The above is all ok when I preview in Lectora.

Any suggestions will be GREAT!

Thanks!:o
