During a meeting yesterday one participant (not the host) was screen sharing a Powerpoint presentation.
All participants except two saw the correct images. However two participants have reported seeing a different static image during the presentation (it seems from their descriptions that it was the same image). In one case the image persisted through the presentation; in the other case it came and went. Nothing like this ever before. Can anyone offer anything by way of explanation? (that doesn't include a reference to Halloween!)
