We have just been working with one gui in Dragon Rider and that works but this was only one gui. If you use only one gui do you still get issues? Thanks
In my project I am uploading and sending you the linky in a pm.
The scene is mainmenu, the GUI is an adaptation of one of the tech demos but worked in the past when compiled but not now, it has 3 GUI's 2 hidden and 1 shown when switching to different menu screens.
