	One obvious possibility is that the projectors are not running. You can look at the lenses and if they are on you'll see some light there. Also, with room lights off, a dark screen is not totally black but has a gray cast and there's a cross where the projectors overlap.		One obvious possibility is that the projectors are not running.

	This should not happen! But, sometimes someone may have changed the source setting for a projector by pressing a key on the hand control. The top two projectors are HDM1, the bottom two are HDM2. To change only one projector and not all, you have to carefully shield the hand control's IR emitter so it is seen only by that projector. Avoid this awkward circumstance by never changing the settings, and by keeping the hand control away from exploring hands.		This should not happen!

	The most likely event is that someone has altered a setting in the Vioso manager. It may be unrecoverable without a total reset, which will require the instructor or a techinician unless you have been taught how to do it. It also takes about 45 minutes, so in this state the system probably cannot be restored for students to use for the current lab. However, there is one thing you can try. Close Stellarium or whatever application you have running, and run the mouse down to bring up the hidden Windows toolbar. Check for the Vioso minimized application on the toolbar, and if it is there, click on it. If it is not there, there is nothing you can do.
