I know this game isn't really about the plot but for some reason I can't read the plot slideshows at the end of each mission.

If I press nothing, the slides don't advance. If I click the mouse, nothing happens. If I press any of the keys it skips the slideshow entirely.

It didn't used to do this - I don't know if it's another El Capitan issue.

Can anyone help? If anyone knows about a clip showing the slideshows that would work too - searched youtube but couldn't find anything in the mass of ROTT 2013 clips.
