title: CEdit selects everything when getting focus
body: <p>When I move to a CEdit control on my dialog using the tab key or the arrow keys all the text in the control is selected. This behaviour is causing me problems and I would prefer it if the control just put the cursor at the start (or end) of the text and didn't select anything.
  Is there a simple way to do this (e.g. a property of the control that I can set)?</p>
