Autoit anti-idle script after screen lock

I'm trying to make an simple anti-idle script (that move开发者_如何学JAVAs the mouse or whatever) to prevent an application from stopping.

How can I keep it running after screen lock ?

It seems like this is explained in the Autoit faq : http://www.autoitscript.com/wiki/FAQ#Why_doesn.27t_my_script_work_on_a_locked_workstation.3F

On locked station any window will never be active (active is only dialog with text "Press Ctrl+Alt+Del") In Windows locked state applications runs hidden (behind that visible dialog) and haven't focus and active status.

So generally don't use Send() MouseClick() WinActivate() WinWaitActive() WinActive() etc.

Instead use ControlSend() ControlSetText() ControlClick() WinWait() WinExists() WinMenuSelectItem() etc. This way you may have your script resistive against another active windows. It's possible to run such script from scheduler on locked Windows station.

You can't automate anything after your screen is locked. User input is simply ignored. A much easier way would be to prevent your screen from locking, for example, by moving the mouse randomly every 30 seconds.
