Divider line in list fields

[Jan Schenkel]

Hi Alan,

I just stumbled onto a small shortcoming in my first
script (to use in case the listfield only allows the
selection of a single line).

should actually be:

  if word 2 of the selectedLine is among the items \
  of tDividers then

Otherwise, the user might still select a divider line
if he clicks onto a normal line and drags the cursor
over to a divider line.
