I've been trying to track down something strange that's started happening on my site and this plugin was one of the last I'd suspect of being the culprit, but it turns out it is. I'm hoping you can help me resolve this because this plugin is great and a critical part.
For some reason if any page on my site is loaded in a frame (such as domain forwarding with masking), the page breaks out of the frame and redirects in the user's address bar. I have clients that sometimes want to point a separate domain to their property listings but not have it be linked to the rest of their site. Because of this redirect, that's no longer possible.
I don't see any option for disabling this, and I don't see any reason why it would be happening.
