Space key problem

Hi there,

Having an unusual problem on one of my slides in a course. Its a fairly simple slide, with 6 clickable images that display a layer each. Once all of the 6 layers have finished, you move onto a 7th layer with further content (progresses on timeline end when all layers are complete). While on this 7th layer, an odd thing keeps happening in that if you press the space key on the 7th layer, whichever of the 6 previous ones you viewed last appears on screen over the 7th layer content. There are no triggers assigned to the space key on this layer, and even if you set the 7th layer to hide all other layers, it still happens.

Any suggestions?

Only thing I can think of is to give the 7th layer its own slide, but that seems unnecessarily long winded.

I've attached a story file with the relevant slide in it.

Thanks,

Kerry
