The problem was indeed in the Keypress event. I solved it by adding the NODEFAULT code in each appropriate case as shown below:
**class txtDate.Keypress()
LPARAMETERS nKeyCode, nShiftAltCtrl

do case
case nKeyCode=13 or nKeyCode=9 && Enter
This.Parent.spnDate.Enabled = .f. && disable the spinner so cursor goes to next enabled control
=dodefault()
case nKeyCode = 5 && Up Arrow, add day
This.Value = This.Value + 1
nodefault
case nKeyCode = 24 && Down Arrow, subtract day
This.Value = This.Value - 1
nodefault
case nKeyCode = 18 && Page Up, add month
This.value = gomonth( This.Value , 1 )
nodefault
case nKeyCode = 3 && Page Down, subtract month
This.value = gomonth( This.Value , -1 )
nodefault
endcase


Thanks for pointing me in the correct direction.
