2.1.130 contained a few very big mistakes indeed. I am probably biased because I've never used stock 2.1.130 :)
I just was unhappy that 2.1.131 contained exactly the wrong solutions to the problems in 2.1.130. You should be able to place my messages into their correct context now.
Alan, you will probably be interested in the VM patch against 2.1.131 I posted earlier. It contains some stuff which should provide 'interesting' enough to stare at for over 15 minutes :)
