Hi, Diane,

Is it possible that you have a Filter active and that, when you edit the vendor, you are changing something related to the active filter? For example, if the vendor no longer meets the active filter's criteria, it will drop off the displayed list and the focus will return to the first vendor in the list. Or, perhaps the number of vendors that meet the filter criteria is very long and when the filter is rerun when you complete your edit this forces the focus to be on the first vendor in the list.
