Any idea why people-picker fields would stop working on forms that have not been touched?
People-picker fields are not working properly on a number of Nintex forms. The behavior is as follows:
If there is more than one people picker filed on a form, the drop down list from a given field is blocked by the ones below it (see attachment for an illustration). This is happening on more than one form. On one form, a people picker filed is not working at all (drop-down never appears).
None of the forms that are misbehaving have been changed recently. Deleting and replacing the field does not correct the problem. Nor does restoring the last known good version of the form.
