[DUG] Detecting screensaver

[John Bird]

I have seen that variant, but from what I saw this detects the screensaver 
is set, not that it is active?

>From the D7 win32 help:

"SPI_GETSCREENSAVEACTIVE Determines whether screen saving is enabled. The 
pvParam parameter must point to a BOOL variable that receives TRUE if 
enabled, or FALSE otherwise."

In my tests the above always returns true, as I do have a screen saver 
enabled, and it does not return a changing status if the screen saver is on 
at the moment or not. (I was using the control panel screen saver preview 
button to check this).

I am trying to detect if a screensaver is currently actually running
