loading message and grey out on slides with MP4
I have a project with a mixture of interaction slides and video slides. There are 10 video slides containing 1024 x 642 MP4's with audio, none of which are over 4mb. The project is loaded into an LMS but reporting is disabled (not required for this project) however some users are seeing the captivate LOADING message with the 4 boxes appearing before and during some slides. The slide video with audio continue to play in the background, the loading message appears and the MP4 and interface are greyed out (semi-opaque). I have tried with preloading set to 100%, set to 10% and disabled but the loading message still appears. Doesn't seem to happen in Chrome, only IE11. User upload and download speeds are in excess of 30Mbps, ping less than 10ms
Any suggestions?
Thanks
Gary
