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.
However, I discovered that placing a dodefault() in the Gotfocus of the textbox does cause VFP to select the contents of a textbox control, even when navigating to the control using the mouse. (Though it does not seem to work this way if the textbox's parent is not a baseclass)
I sure don't get warm fuzzies when an explicit call to the parent's gotfocus clearly does something different than the implicit call that supposedly gets executed when one leaves a method empty.
