Issue displaying frames in Chrome

Hi all -

We are currently using RoboHelp HTML 7.0

When I publish, frames cannot be viewed when using Chrome, although they are just fine when using IE or Firefox. This is the publically shared URL for accessing this file - http://responsibility.motorola.com/web_help/index.htm

I've been told by co-workers this is not a version issue, it does not work for higher versions of RoboHelp either. Does anyone know the accuracy of this statement? As Motorola is now owned by Google, it's obviously of concern.

Note that I have installed IE extensions for Chrome, it did not make a difference

Chrome:

Firefox:

Thank you,

Anahid
