Slide background Images not appearing?

Slides background images appear on the screen of the computer where the presentation is being created, but backgrounds don't appear on remote the remote computer- they are blacked out, this has never happened before?

Hi Kurt, please send a few screenshots to [email protected] so we can further investigate. Thanks!

Thank you, just sent an email to you.

Kurt, I had this problem I found it was that the media library was not synchronising properly.
Try the latest Beta (beta 16). This fixed my problem; see if it fixes yours.
