Hi Peter,

>>>>>>>>>>
1) Make sure the EDITBOX.SELECTONENTRY property is FALSE.

2) Make sure the EDITBOX.FORMAT property is empty at design time.

3) Make sure the EDITBOX.FORMAT property is empty at run time.

4) Place this code in the EDITBOX WHEN method:

THIS.SELSTART = 99999
RETURN .T.
>>>>>>>>>>>

these are a not necessary restrictions.

Next conditions are sufficient:

1) Make sure the EDITBOX.SELECTONENTRY property is FALSE.

2) Make sure that 'K' $ EDITBOX.FORMAT it is false. 

3) Place this code in the last executed line of EDITBOX GOTFOCUS method:

     THIS.SELSTART = 2147483647

But these not resolve the mouse set focus:
For this, you can use next schema:
set 1),2)

3) Place this code in the last executed lines of EDITBOX GOTFOCUS method:
    THIS.TAG = "G"
    THIS.SELSTART = 2147483647

4)  Place this code in the last executed lines of EDITBOX CLICK method:

    IF M.THIS.TAG == "G"
         THIS.TAG = ""
         THIS.SELSTART = 2147483647
    ENDIF
