Autorun and popup menus in Manipulate

Questions

1

I have a notebook running a manipulate structure of which two controls are popup menus that a user can select a row of data from a large list. It works well.

My problem and question if I engage the the autorun feature the variable updated by the popup menu becomes blank at times. This causes a program crash. Can I remove a control from autorun or should the popup menu be removed from the manipulate?

Can I remove a control from autorun

Yes you can, by using the option AutorunSequencing. The example below excludes the b control from autorun.

Manipulate[
  Column@{a,b,c},
  {a,10,19,1},
  {b,Range[20,29]},
  {c,Range[30,39]},
  AutorunSequencing->{1,3}
]
