	Not necessary. In my example, - Mousotron, - collects number of keypresses, 
it doesn't log anything (it even lacks statistical logging). In real world 
this program is useful to see how much text you wrote today or how actively 
you used your mouse.

	Well, fact is that (unfortunately) not all developers of Windows programs 
really care about good design or good practice. BTW, I'm not sure how exactly 
Mousotron works (I didn't actually tried to debug it) so therefore I'm not 
sure does it uses this function or not; I just think that there is might be a 
such possibility.
