And thank you VERY MUCH to soja...
Gosh, you're welcome. My pleasure. <blush> =)
Say, that's a pretty neat little "Laundry Timer" or "Egg Timer" program (as many people call something like that). I did find a couple small issues, though:
1) When the target is reached, and the notification is displayed, if the user clicks Cancel, the Start button is still shown as deactivated and the Stop button is still activated (even though the status is idle).
2) There's an interesting behavior when the user enters negative numbers... how long do you think it will count? =)
(It gets more interesting when you enter very large numbers, like 2^32-1, but that's no big deal...)
