Light box effect showing up in dashboard interface?

Light box effect showing up on dashboard interface?

Hi All,

So I am having this mysterious problem where the lightbox/ shadowbox effect is showing up on all things I press?

So, once I am logged in
I press on a anything like add a new post, or to add a title, then the lightbox effect pops up showing no image but the standard block and loading bar with the screen darkening.

I am using a yootheme. But this happens **within the dashboard of wordpress**
On the front end of the site there is no problem…. its just in the dashboard.

I disabled all plugins that had that effect and it also continued to do the same thing, even after flushing my cache through terminal, deleting cookies etc…

This is a real “who done it?” Any ideas wha’ts up?
