John, you're right about the "\" not existing in the Value, that's why I was doing this:

[\] + THIS.VALUE

As far as the mouse, if you click on a disabled item, focus automatically moves.

>Dave,

>>>Dave,
>>> I don't think it's documented very well if at all but you can disable a line on a listbox the same way as in a popup. Put a "\" as the very 1st character on the line. ie:
>>>Thisform.lstDates.AddListItem('\ this line is disabled',1,1)
>>>
>>>Hope this helps,
