WP-34S: Stopwatch - bug, feature, or user error?

[pascal_meheut]

When stopwatch is running, automatic power off is always ignored. Stopwatch can run for hours.
The problem occurs when stopwatch is not running, i.e. just stopped but we are still in stopwatch mode.

I had a mode detailed look at the code and in this case, stopwatch stops itself after 3 minutes, line 469 of stopwatch.c:

} else if(StopWatchKeyticks >= STOPWATCH_APD_TICKS) {
KeyCallback=(int(*)(int)) NULL;

So a solution is to increase STOPWATCH_APD_TICKS to a few hours... One can suppose that using the WP34s to measure time, stop it for hours and then restarting it is a very rare usage.
