Sigh - had to fix latest release of Java on the Mac

For some reason on my computer, new versions of Java just don't work
correctly - they insist on trying to load the Input Method jars:

indicim.jar     thaiim.jar

So, to make everything work, I have to copy them into the correct place.

cd /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/lib

sudo cp im/*.jar ext

After this everything works normally.
