Zenworks agent
Windows XP SP3
Management station: IE 8, 9, and 10. Firefox 17.0.5, Firefox v22.
Client: Firefox ESR 10.0.11, 17.0.2

When remote controlling from either Firefox or IE there is a blank window on the client-side copy of Firefox.

Here is a video showing the behavior.

This is proving to be a bit of a problem for us since we are in the process of trying to standardize our client-side browser version on FirefoxESR 17.0.2. Is there a workaround?
