This bug has been fixed in SP1.
To make the first row selected

Thisform.Listbox1.Listindex = 1

>Does anyone encountered this listbox error message when you tried to press the Enter Key when there's no record being/is highlighted in the listbox.

>This happens when i created a form with listbox(list of customers are displayed for selection that returns a value selected from it) and called by my transaction data form. when the form is called/activated it displays the list of customers without any of the list being highlighted first. When i click on any of the list then it gets highlighted or click any of the list and scroll to make a selection by pressing Enter Key, it returns that value and no error at all. But when i tried to Press Enter Key first right after the form was called without any item in the list selected or highlighted by clicking it with a mouse, It returns an error and VFP quits the programs.

>Another thing. how can i make the first list/record in the listbox becomes the default record highlighted or selected just like in the combobox when you activate it, the first record becomes the first record highlighted?
