Hi, Owen.

This doesn't look right. Try with ControlSpy and you'll see WM_SETFOCUS 
sent just after LButton pressed on
client area (not on item, that's important). LButtonUp event used to set 
focus item was under mouse pointer and it's
released without any mouse movements (or maybe drag threshold doesn't 
count).
