Speed of processing actions

Because the macro runtime executes actions much more quickly than a human user does, unforeseen problems can occur during macro playback that cause an action not to perform as expected, because of a dependency on a previous action.

One example is a keystroke that causes the application screen to change. If a subsequent action expects the application screen to have already changed, but in fact the application screen is still in the process of being updated, then the subsequent action can fail.

Timing-dependent errors between actions can occur in other situations, if the macro runtime performs each action immediately after the preceding action.
