Ah-HA!!!! The mystery is solved! And it was Sky's comment -
it was in the viewing settings under advanced...for the computer that turned the light bulb on.
I use Firefox as my primary browser, but there are a few things (such as some graphics and sounds) that are quirky in it. I opened the site with IE and, voila!! No problem at all!
Thank you so much, Sky, LMo, and Petunia for your help and adding some humor for the day.
Good to see you all...off to check out this new moods thing!
