Understood, Dragan.
My reason for uncertainty in this regard stems mainly from VFP's "Timer" operation. This led me to speculate that there les to the whole thing than meets the eye.
I suppose that I was just being too sensitive to one specific factor, letting it blind me to the rest of things.

>Just yesterday I spent some time playing my solitaire (it's in the Files) and observed one thing again: when I finish the game, a modal form pops up (a "another game" "yes;no" type) - and it pops up before the last move was actually shown - and the amount of code which happens between clicking the last move and the appearance of this modal window is not neglectable. You can actually see the main game window still being updated in the background. I'm not saying I've observed multithreading or anything of the kind, just that there's some queueing of paint events which doesn't necessarily reflect the chronological order of the events which cause them. I think the request for drawing a new form has a higher priority than the refresh of the background form - and I really don't know what does it mean in terms of threads, timeslicing, OS and whatever. Just had to make a mental note that this may happen again under some other circumstances, and that I shouldn't be surprised.
