[Bug 13683] Ultima IX: Mouse pointer missing when reading books, under inventory

https://bugs.winehq.org/show_bug.cgi?id=13683

--- Comment #52 from Christopher Thielen  ---
I can confirm the following patch resolves this bug.

It also causes Wine to correctly mimic Windows' behavior in my demo. I am not
sure why the original author of user32.dll was making the check I removed. Is
there a good way to determine who has solid knowledge of user32.dll to ensure
I'm not removing behavior erroneously?
