I first wanted to point you to my St.opwatch abstraction, to find out you seem to have found an older version of it in the archives... ;-) To make it working for you, you just need to make the metro bang faster. Then it wouldn't skip seconds. use something like 100 ms... Then I'd just take a prepend set and a maximized message box instead of the LCD, way easier... There is one advantage over the audiorate example. It doesn't need a snapshot (very expensive) and it would count correct if you switch off audio, and even would survive and keep the correct time if you set the computer to sleep... ;-) Stefan #P window setfont "Sans Serif" 9.;
