I recently installed SN7 enthusiast on my iMac. I have noticed that when scrolling the sky around, I get occasional flashing images. They are so brief, almost subliminal, that I have not been able to see what they are, but yesterday I managed to see two images, which were 1) an image from a soccer match that I had watched earlier on BBC iPlayer, and 2) an image of myself from the iMac's camera, which I realised was from a 'FaceTime' call I had made earlier in the day to my grand-daughter.
I appreciate that this may sound weird, but it actually happened! what's going on?
