I configure in the general preference tab "use file compression" and when save for first time (Save as) I can save .PZZ file, but when save the same file again (save)Poser 5 generate a new uncompress Poser file(.PZ3) and not overwrite the first original .PZZ file. This happen always when use "Save" and when use "Save as" Poser 5 work fine. Of course the solution is use "Save as" and overwrite the .PZZ file, but I lose time. I have installed the SR3. I need help for fix this Problem. Tanks. Sorry for my bad English.
