I can't play videos fullscreen

If you're trying to play videos full screen from your browser, you'll need to use either Google Chrome or Firefox.  They are both free browsers, they run on Windows and Mac computers, and they work very well.

You can download and install google Chrome here:

If you prefer, you can download and install the Firefox browser here:

While some things work well in Internet Explorer (IE)...  most things work better in Chrome and Firefox; especially full-screen video viewing. 

We recommend upgrading to one of these great free browsers.
