Thanks for the info! While the print statement itself may be delayed, I believe something else is going on here. I added this code on:
var SelectedItem = self.get_selected()
And the same occurs with the collapsing/uncollapsing of the cell. It is delayed and not in sync with the mouse clicks. It allows the collapsing to occur about every second, same time the string is printed, versus whenever a cell is selected/clicked on.
Appreciate the insight, hopefully this is something simple as well.
