Hi!

Originally, mouse supposed to set the text cursor to the point in the text where mouse clicked. Thus, when clicking by mouse on textbox, event when SelectOnEntry is .T. and FORMAT is 'K', the textbox gets not selected. Calling 'this.SetFocus' in the GotFocus or Click event of the textbox solves this. You seems found another solution. In your case, dodefault() runs the default behavior of the GotFocus event one more time. Thus, first time it runs, puts the text cursor where mouse clicked, than second run of the default behavior of the GotFocus cause text selected again.

Seems this functionality is clear...

>It is a documented 'feature?' that the SelectOnEntry=.T. property only takes effect if one uses the keyboard to switch the focus to a Textbox control. In particular, if one uses the mouse to select a control, VFP does not select the entire contents of the control when the control gets the focus.
