Thanks for explaining your changes, both here and in the ChangeLog.

None of the links you provided mention the behavior of NPAPI on 64-bit Windows.
This one:

Talks about WPARAM and LPARAM from windef.h. But I don't see any evidence that
_NPEvent's wParam and lParam are supposed to follow those definitions. Do you
have information regarding what 64-bit NPAPI plug-ins expect on Windows, or
what other browsers do in 64-bit?
