Hi Steve,

> Saving / reloading to make simple boolean is really quite a strange way of working.

It is, but this should only make a difference in a few particular instances, it isn't something that you should need to do on a regular basis or anything.

Please let me know if you run across this more frequently.

Of course it is something that I would like to fix up - in this case the bug is not in my own code but in the geometry library that I'm using.
