--- Comment #16 from Zeb Figura z.figura12@gmail.com --- (In reply to Zeb Figura from comment #15)
The wine-staging patch is wrong; WM_SETTEXT is not enough to trigger the MDI menu to refresh. Unfortunately there's not really much else that happens in the MDI code, so I'm not sure why this works on Windows. Also unfortunately, Word Pro 9.8 doesn't work on the Windows version I have immediately available, so I can't confirm that e.g. something changed in Windows.
Turns out WM_SETTEXT does trigger a refresh, but there's some sort of check in Windows that the menu is actually... visible? attached? Not sure what, but adding it to the frame menu like Word Pro does is enough to make the tests work. I've submitted 8967.
