This should work just fine.  Perhaps your configuration is strange, or your
boxes are big enough to run off the end of a signed short (2^15 - 1).  The only
client I know of that does this sort of thing is xmh, so perhaps you can look
there for an example (although I hesitate to mention this, since the xmh code is
to twisty, but if you are brave you can take a look).

If you can provide a short example that causes the Viewport to fail, please
submit a bug report using the form provided in "lib/doc/bugs/bug-report" in your
X tape.
