Hello Martin,

I am happy to inform you that a solution has been found to supress the 
subwindow error :-).

Since the card is waiting for a mouse click, I have simulated the mouse
click with the click command. Even then I didn't get the desired result.  
So, I have set the button menu mode to 'Option' prior to click on the
button and then reverted to 'Combo box'. The following script is working 
perfectly.

on arrowKey theKey
  if theKey is "down" 
  then
    set the menuMode of btn "micron" to option
    click at the loc of btn "micron"
  else
    pass arrowkey
  end if
end arrowKey

on menuPick theItem
  set the label of the btn "micron" to theItem
  set the menuMode of btn "micron" to comboBox
end menuPick

I still wonder why the popup command has been causing the subwindow error. 

Thank you very much for your interest in solving my problem.
