Wow, thanks for the fast response from the man himself. I'm a bit baffled, though, as I thought what I had was the latest release, version 1.2.8, which doesn't seem to have the enhancements you mention. I'm guessing this is because its in the currently cvs code which I would need to get, rather than get the released version?
