7 years ago Yep this is a known problem that appears because the standard popup controls eats the click event completely and only lets it through AFTER it is closed. That means the nodes are reordered after the selection is made, which confuses the control ID system and assigns the value to the wrong, previous node... Haven't yet found a solution to that, unfortunately, other than replacing all popup controls...
When there are two node, modify one EnumPop first, and then want to change to another node EnumPop, it need twice click to modify otherwise it will modify the first node, because the focus has not changed。
