At some point, there was some hassle about what coordinate system the "where"

Browse Source 
BPoint in a mouse moved message is. Turns out it's different (!) according
to the type of message and this is even documented in the BeBook. I don't
really know if we want to copy this, but since there are apps out there that
depend on this, I am implementing it so that it's compatible with BeOS: In
the B_MOUSE_UP/DOWN case, it's the coordinate space of the target view, in
B_MOUSE_MOVED messages, it's that of the window. That explains a few things...
Clicking into Pe's function popup window should now select the right icon.
