Hi again. OK, I have played with settings in my email account and can provide the following info. First to confirm the problem, it appears to happen when I scroll through the daily digest and come to a post with a video attached. For example in the today's daily digest, I get as far as the topic: Running Engines a little our of the mainstream and the post by BANDOB. All fine until I get to that point, then screen goes black for the rest of the entire digest. Now here's a possible resolution: if I go into my mail preferences and in the Viewing page, uncheck "Load remote content in messages", the black screen disappears! If I recheck it, the black screen reappears. If I uncheck the box, I also lose some other info, such as the OGR banner. Not sure I want to keep that box unchecked, but I may do it just to review the daily digest.
If you have any other thoughts or suggestions, I would appreciate them.
Thanks,
Michael
