OK. Here's what happened;

SUCCESS:

I followed the path Tools > Internet Options > Settings > View Objects...that was as far as I could go because in the list of "downloaded program files that appeared, there simply was no QuickTime file or folder.

Then I went C:\Program Files\Quicktime\Updater.exe (which checked and said: "You don't need an update." Fine. I next clicked on the file called "Movie Player" which brought up the Quicktime player. I told it "Play" and it said "Some files are associated with other players" or words to that effect. It then asked if I wanted to change those files to be played by Quicktime. A bit desperately I told it "OK" and the movie clip played.

So then I went to the www.spinmaster site, right-clicked on the bubble demonstration link, clicked "Save target as." It downloaded the file in a flash and stuck it on my HD. From there Quicktime played it without dificulty.

So thanks Everybody. If you have managed not to get tired of me, I'd love some input on the following 2 questions:

1. But does anyone have an idea why I had to download it to my HD in order to play it?

2. And why was Quicktime not in "View Options"...I mean clearly it was on my HD and functioning?

This same situation happened earlier with Windows Media Player and a mpeg file on a site. Except that a few days after that, I was able to play the mpeg file simply by clicking on it at the site. (That is, I no longer had to download it to my HD first.) I've no idea what caused that change.
