I've been struggling with this script today (JMP 13.0.0 Pro). When a insert a combo box in a tab page box, it becomes really slow to react to a mouse click, as if the combo box is not getting the mouse event, This happens only whenever a second tab page box is present. It looks to me like a bug, but I might be missing something. Any idea?
new window("a",tb=tab box());
tb<<add("1",tpb1=tab page box());
tb<<add("2",tpb2=tab page box()); // if I comment this line, everthing is ok.
