QB Issue Resolution:
Its supposed to work as you describe with the text selection starting after what you’ve typed (leaving the “guessed” part selected). I haven’t heard of it working otherwise.
Are you running Yosemite (OS 10.10)? If you reboot your machine holding down the shift key does that fix it?
