After selecting a number of records and then executing a LUA script the selected items remain highlighted.  When selecting different items the originally highlighted items remain hightlighted.  Scrolling the items off the window and then returning to them clears the highlighting.  The highlighting is also cleared when the screen is changed, move to a different notepad and then return.
 
It should be noted that it is erratic in that though the behaviour is repeatable sometimes all of the text remains highlighted and at other times only a portion of the text.
 
There is no negative impact on the data.
