WebGL Build: Clicking while loading hides GUI

Hi All,

I've been working on some WebGL content and have deployed (fairly) successfully. The only problem is, when the content is loading; if the user clicks, the UI is hidden on load. Here's an example build to show you what I mean:

If you click whilst the Unity Loading bar is onscreen, the GUI doesn't display properly.

Do I have any access to what happens whilst the loading bar is onscreen? Are the Awake and Start methods executed before this screen disappears? Is there a way to force the UI to redraw like there is in an Inspector window?

Any tips or nudges in the right direction would be greatly appreciated.

Thanks,

Matt
