I kind of guessed it was a 64-bit issue, which was why I tried installing
the 32-bit Python (though at the time it occurred to me that it could also
be an ActivePython issue, so I figured I could circumvent both
possibilities by switching to the "official" 32-bit Python build. I will
stick with 32-bit for the time being. I agree that there seems little real
motivation at the moment for trying to go 64-bit with TW.

Another thing I have wondered (and a post you made a couple of days ago,
directed at Jonathan, recalled it) is: Would it be much work for me to do
a build similar to his distributions? When I first installed using his
distribution it set up Program Files\TeXworks, with a single large
executable and a few support files. When I build by the instructions in
the Wiki, I get a smaller executable and I have to include a bunch of
extra dlls. Is there a way to build the single large executable this way
and just place it on top of the one from Jonathan's distribution? I
currently have copied all the dlls to that directory and overwritten the
executable, so the setup is functionally equivalent. It's not a big deal;
it just feels like it would just be a bit more elegant if only needed to
replace the executable.

Speaking of the Wiki, it might be worth noting in there that the Lua and
Python plugins (if they are to be included) have to be compiled BEFORE
compiling TW (at least on Windows).

Thanks again.
