Chrome and text_field_with_auto_complete

Having issues with an auto_complete field on my rails app with users who
use Chrome. The field does not allow you to choose anything when a
selection is highligted and choosen. Was just wondering if anyone has
fixed this problem or has found a way around it by using something else.
My problem is that I am choosing from a rather large list and would like
this field not be to your average everyday dropdown. Thanks,
