Air Display Turns Off After 10-15 mins - Why? What's the fix?

Question

I recently upgraded to OSX10.8 on my early 2012 mac mini. I have been using AirDisplay as my screen.
I've run into an problem. The AirDisplay prefpane now turns itself off after 10-15 mins if its not being used. It also doesn`t activate on reboot.
This is obviously a problem as I don‘t have a monitor.
I started to use logmein instead, but its not ideal as its mouse isn’t quite as usable (it works in the current release after many months of bugs and patchy performance).
I've been going back and forth with Avatron for a few weeks (they've been very supportive), and they proposed two solutions:
Uninstall / reinstall using a newly downloaded package
Delete the hidden com.avatron preference files
Neither has worked.
I also made a rather pathetic to write an applescript to select the menu app item "Turn Air Display On" , but I didn't really know what I was doing (here's my poor effort below). As I didn‘t get this working when the menu option was available, I didn’t proceed.
tell application "System Events"
     set UI_Enabled to UI elements enabled
          tell application process "AirDisplayStatusItem"
          entire contents
               tell menu bar 1
                    tell menu bar item 1
                         click menu item "Turn Air Display On"
                    end tell
               end tell
     end tell
end tell
get entire contents of application process "AirDisplayStatusItem" returns
--> {menu bar 1 of application process "AirDisplayStatusItem", menu bar item 1 of menu bar 1 of application process "AirDisplayStatusItem"}
Result:
error "System Events got an error: Can’t get menu item \"Turn Air Display On\" of menu bar 1 of application process \"AirDisplayStatusItem\"." number -1728 from menu item "Turn Air Display On" of menu bar 1 of application process "AirDisplayStatusItem
Has anyone any ideas on how to resolve this?

This may be a Windows 8 issue. I finally fixed this problem by identifying the screen saver as the issue (and I wasn't using a screen saver). Type "lock the computer" into the search box after clicking the search charm, which brings up the screen saver dialog box. Mine was set to 1 minute, though I'd never set it myself. If you can't change it, choose a screen saver and you should be able to do so (and can then switch back to no screen saver). BUT, here's the problem. Other things you install (or settings within things you install) can apparently change and override whatever you type in for the delay time. Try applying your new time and exiting from the dialog box, then open it back up again. I was finding that it kept going back to 1 minute. To reset things so that you can get control again, type "user accounts" into the search box and when the dialog box comes up, choose "Reset Security Policies". Then you can go back to the screen saver dialog and successfully change the delay time.
