Paste buffers should work from any window to any other. If not, its a
bug.

If you've got the _same file_ open in two windows, then you're asking
for possible trouble and data-loss. Bonus points for the fact that the
auto-save backup will probably use the same filename for both, and
you'll have no recovery means.

I might be wrong, but I didn't think gschem / libgeda would _allow_
opening the same file twice.
