When I open up my home page and there is a video to watch on it, the video is sorta blacked out or it is not seeable. If I move the page up and down I get to see it for a brief moment and then it is gone again. If I can get it to open in full screen I have no problems seeing the video. What can I do to see a video without having to pull it into the full screen? This also happens when I get on youtube also. Sometimes I can't find the button to go to full screen. Any ideas? I am a teacher and need to look at many videos before saving them for my students to watch.
Thank you for all your help.
