Hi Naomi,
I have this code in our ChkBase class MouseUp Event.
PROCECURE MouseUp
LPARAMETERS nButton, nShift, nXCoord, nYCoord
IF This.ReadOnly
NODEFAULT && This prevents the buffer from getting dirty when this control is ReadOnly.
ENDIF

If you set the checkbox to be readonly and try to click on it and you would have table-buffered local view with the field bound to the checkbox, would GetFldState or GetNextModified return a change status? In our case the system thinks that a change was made.
