Ah, found it at last.
I wasn't correctly detecting the presence of the right proxy in Mousedown, and
further, returning false doesn't seem to trigger gotFocus.
So changed the mousedown event handler to:
'if ftEditProxy = nil then return false
if editIndex <> index or ftEditProxy = nil then me.SetFocus
' Invoke the event.
return ftEditProxy.callMouseDown(x, y)
and all seems to work now.
Thanks for your help.
