We are experiencing a problem with the Search and Auto Complete feature on some pick list fields. Our users love that the forms load faster in the case of very long  lists and love that the search feature in addition to 'starts with' handles 'contains'. But, the pick list does not always populate with all the available selections. We understand that with the Search and Auto Complete option selected, by design the pick list only partially populates until the user requests additional items via search or scroll down. However, in some cases, the field does not populate past the initial load even when the user attempts to see more. Strangely, in some occasions but not all, we have observed that refreshing the edit-record will allow the field to fully load. We experience same in both IE and Chrome.

 Is there possibly a browser setting or a time-out issue that could be causing this to happen?
