[Doggiebox] Changing time signature for whole song

I have a dbsong which is all in 3/4, but I'd like to change it to 6/8. However, I don't seem to be able to select the whole song and make the change effectively, or even select a whole section of multiple bars and make the change. Or, rather, if I try to do these things, DB seems to change some bars, but not others -- resulting in some curious weirdness. I seem to be only able to successfully select a bar at a time and make the time signature change. Any suggestions? Cheers, Carl -- Carl Edlund Anderson http://www.carlaz.com/
