Why are Web Objects (Engage) moving when expanding the menu

Hello,

I've added some engage elements as web objects using the standard Articulate process. Publish to web, change the .html file to index.html edit the html.

They work fine when published, no problems at all.

The issue that I have is when you collapse or expand the side menu the web object doesn't keep up with the slide background. The web object moves a few seconds after the slide background moves making the presentation looking a little clumsy.

Has anyone else come across this?

Things that I have tested and it still happens:

• Web output
• CD output
• IE
• Firefox
• Locking the presentation size
• Testing different presentations
• Local version and internet versions

Any help will be greatly appreciated.

Many thanks,

Scott
