Disable Region Preview

Hi,

I've just upgraded to version 1.4 and have seen that the layout design section displays a preview of the content shown in all regions. I've discovered a few issues with this and would like to know if the region previews can be switched on and off. I've so far noted the following:

1) We stream live freeview TV in via a web page that uses the VLC plugin to pull a multicast stream. When we want to have a region on a layout with some live TV, we simply set the region as the relevant web page and the VLC plugin does the rest. We've noted that although the preview plays the live TV stream web page without issue, we can't then right click on the region to bring up the menu with the Timeline, Options, Delete and Permissions sections. The video plugin that plays the stream in the preview seems to block the appearance of the menu.

2) If we set a web page in a region, the right click option for the Timeline, Options, Delete and Permissions only works when hovering over a section of text. If we right click over an image on the web page shown in the preview, we get the standard internet explorer menu appear that delivers options such as view source or download image etc.

Ideally we would want the option to be able to toggle the region preview on or off, and if this isn't possible then have the option to disable it all together.

Hope someone can help.
