1. Fire up kword and start with an empty document
2. Type 'abc'
3. Press Shift+Home. The line is selected.
4. Type 'def'. Rather than replacing the selected text, you end up with
'defabc' and nothing selected.
5. Or so you thought. Move another window over kword to force a redraw.
Now 'def' is selected and 'abc' isn't.
