Hmmm...wish I had known that. It was just kind of shocking to see it happen for the first time. Wont that eat up your harddive though? Before this I had just saved as PZZ (compressed PZ3) files. Even then when I open up the saved PZZ make a change and then save again, P5 will save as a PZ3 instead of saving on top of the PZZ. Only way I've been able to get it to save over something is thru the "save as" option. Dave
