Why is LastPass for Applications so slow in filling?
LastPass for Applications takes timing into account during training, to take account those cases where some fields or dialogs may not be visible right away. During replay, it replays the delays as well. To speed things up, re-train the applications and reduce the delays between entering fields as much as possible.
