Thanks Ed... that fixed things (obviously I need to update my OS skills from the dark ages of W95 !)
However, as you probably know, if I try to change the preview to some other screensaver I get superposition of your example with the other one (i.e. it is not getting an 'end' command)
Also, your saver does not appear in the drop-down box if I close then reopen the Display Properties control panel.
There may be a case here for hijacking the entire Windows message queue and using PeekMessage to find what you are looking for. May also need GetHWND("Windowpanel") or something similar, and then there will probably be different names for differnt OS verions. I will try to investigate if I get a bit of time...
