Code Editor not opening up in Upfront....


I seem to keep encountering a little bug whilst working with Upfront.

I have dragged a code element into a page on my site but the usual code editor that pops up at the bottom is not opening up for me.

Double clicking on the code object usually works for me -- but not this time.

Clicking on the settings cog icon does not work either. The only option is to write code into the visual interface on the page, which is not good at all as it's very clunky and I cannot access the CSS Panel or the other panels, and also the embed link option.

Is there a way to trigger the panel manually?
I can't seem to pin pint why it's not opening up....I've attached a screen shot of the code element on the page, but I'm not sure if that's going to be any helpful or not.
