Greetings!
Here's some pop-up menu results I've reduced from data captured on my
Tektronix Magnolia running 3-buttoned Smalltalk. Smalltalk menus pop up
showing the previous choice selected for the window or the last item
highlighted before moving out of the menu (eg, when it turns out to be the
wrong menu, or the situation is discovered to be inappropriate).
The times do not account for all the system overhead of displaying,
data logging, and removing the menus. The clock resolution is 1/60th
second. The relative average times and percentage of occurance may be
useful, however.
