A Java Web Start program I wrote a long time ago suddenly stopped
working.  It sets the System clock to an atomic time server.

I discovered the problem was it uses a 32--bit DLL via JNI  and my
default Java is 64 bit.  It cannot use 32-bit DLLs.

That surprises me. I would have thought MS would have had to come up
with a way of doing that since so many DLLs would not yet be available
in 32-bit.  Maybe it can in general, but just not in Java.

For me, the appeal of computer programming is that
even though I am quite a klutz,
I can still produce something, in a sense
perfect, because the computer gives me as many
chances as I please to get it right.
