--- Comment #2 from Ken Sharp imwellcushtymelike@gmail.com --- Went back to Wine 1.6.2 and wordpad does still remain in memory, so it doesn't look like that is a regression.
The result being that any application that expects a reboot after installation requires an actual reboot (or kill wordpad and let wineserver exit), if a user has tried to print using this method.
Wordpad needs to exit after reporting the error, but it doesn't.
