About every other time we try to power down our iMac the normal way, we get a gray message box instructing us that we have to use the power button to power off.  The message appears in five languages and reads as follows: "You need to restart your computer. Hold down the Power button until it turns off, then press the Power button again. Please respond if you have received this message. What do you think causes it?  We are on the Lion operating system; we have not yet upgraded to Mountain Lion.

iMac, Mac OS X (10.7.5)
