--- Comment #7 from PennRobotics  ---
A few remarks---prefaced that I don't know much about Wine or Windows:

* There is no WindowPosChanging in the middle (at or around 13:34:50), and this
is expected as AFAIK the plugin window doesn't change its origin; only the
parent window, owned by REAPER, moves. I see there's a window for the whole
screen (10072h) and for the plugin (2000003h) and I don't see anything about
parent position in the debug log: all of the GetWindowRect lines start with
(0,0). However, the offset used by map_event_coords changes from 13:34:49 to
13:34:51, so this is when I moved the window.

* There are only two MouseEvent pairs where there should be six (if those are,
indeed, the mouse clicks) and they are both occur higher than (100, 100) where
the first one should be closer to (0,0). These clicks would have been after I
moved the parent window (up and left).
