ION monitor setup woes

Question

bit of a lengthy post coming I'm afraid. We have an ION with 1 VGA screen as main screen, and 1 Kristel touch screen as 2nd monitor. We're running the latest version of the software. 
 Things have been running tick-a-dee boo until lately. On power up, both screens show the splash screen, then the ION screen, then monitor 2 loses signal. I go into SETTINGS>GENERAL.EXTERNAL MONITOR ARRANGEMENT and see the 2nd screen shows as available so I click on it, then click below to add it, then click ADVANCED, scroll down and see Monitor 2 is not enabled. So I enable it and set its MODE 1024 x 768 16 Bit @70 HZ. I click APPLY>YES then ACCEPT. 
 At this point I've tried both of the following: 
 1)Click on Primary to start things up and no monitor 2 and/or: 
 2) Power down and restart. 
 Both procedures no 2nd monitor. when I go back into SETTINGS, I see that the changes I made have not taken. 
 Suggestions?

With both monitors attached, try holding Control + Alt and F12 (or, if you have the mini keyboard, Control + Alt + Function F2), and you should see a window with some options. Make sure "Extended Desktop" is selected.

 Had the same problem, even once I started using two dvi monitors 
 this solution solved the problem instantly - it was driving me crazy, I had done multiple software reisnstalls etc. Thanks luke
