Does anyone with a business license use the script profiler? I'm
having trouble interpreting what it reports. According to the lesson
in the LC Lessons, it looks like the most recent handler is recorded

without any order that I can see.
I also deliberately repeated a user action three times, and the stack
responded correctly, but I only see one instance of the handler in
the profiler. Is that normal? Or should it list every occurance?

Then it reports the number of calls and the cumultive time for each
line that was called. The times are relative to each other, not the
real times without the overhead of the profiler.
But they give a good indication of where the bottlenecks are.
Thank you, I do see the same thing, now that I know what it's doing.
That makes sense.
I took a different approach in the new PowerDebug. I display the lines
of code as they appear in the script, in order to preserve as much
sanity as possible. The singleton and aggregate times are both
displayed, with the singleton times rounded up to the nearest
millisecond because that's the limit of LiveCode's accuracy. However,
hovering over the time will show a better indication of the actual time
if there are multiple iterations because of averaging over more data
points. And any times over 1/2, 1/4, or 1/8 of the total time are
flagged in color to alert the developer.
