Your computer is ready with your ActivInspire lesson. You look at the computer and see this:
But when you turn on the projector aimed at your Promethean board, all you see is something like this (your computer's wallpaper and no programs, not even your dock):
This tutorial will show you how to fix the issue.
Note: If you really like this wallpaper, it's availble on Flickr (or you could grab it from the above image, as that is the wallpaper). The image is called "Bokeh Effekt - Wallpaper", the artist is named "bayfan". The image is listed as having a Creative Commons Attribution-Noncommercial-Share Alike 2.0 Generic license [you can legally share it]. And the link to the image is http://www.flickr.com/photos/bayfan/4121098491/ which is blocked by ENA's web filter, so you may want to get it here.
If you have your computer hooked up to another display device, such as a TV or a projector, you can show the image on your computer to the other display device (the projector, in this case).
That should fix it.
You can unselect Mirror displays if you want something on the overhead, but not showing something confidential (like your email, or gradebook, etc.). So it's technically not a "dumb thing"; it has its purposes.
Whether you undo mirroring or power off is a situation call. If you get a chat request, and you expect it to be a brief exchange, such as "I need you to come see me regarding a purchase order" to which you reply, "OK"... it's probably more effective to turn off mirroring and reply privately that way rather than turning off the projector and being forced to wait 15 minutes for your class to continue.
