I'd be careful about that assumption.  There are a lot of
components involved.  I don't remember whether anything else
changed at the same time.  For example, I might have started
using different versions of Windows and eXceed (I know
those two go together, because of the way machines are
provisioned at my employer).

What I remember was building Emacs 24.4 myself on Solaris
for the first time in almost two decades.

I might also add that I have variability of paste behavior.
Sometimes, Control-y pastes from the X buffer and sometimes
I have to use Mouse Button 2.  MB2 always does it.  I don't
understand why C-y has variable behavior, but I have similar
challenges in other X applications, so I'm pretty sure
/that/ aspect is about eXceed.

Sure, that might help.  I'm not afraid to get into the code.
I just haven't assumed it's actually an Emacs bug....
