Tech question

I've noticed that, over the last couple of days, my embedded videos don't seem to be working when I access them from my Dell desktop. They work fine when I access from our Mac laptop. I also noticed that when I try to activate videos on other Blogger sites, they're not working on the Dell, either. I updated the Adobe flash player, but still, no dice. Interestingly, I don't seem to have any trouble with videos accessed directly through the YouTube site. Let me know if, going forward, you can't get the embedded videos to work.
