Greetings all.
I experienced similar frustration with window sizes, locations, and viewing parameters in Word. I work with multiple documents open concurrently and on multiple displays. This problem is especially frustrating in such environments. Consequently, I just finished a lightweight add-in that nicely takes care of it! Word only restores the application's last view parameters. The Deja View add-in retains the last view parameters per document. It is open source and free!
Deja View (Microsoft Word Add-in) [Moderator's note: Commercial Add-In]
Let me know if you like it.
Best regards,
Manny
