Well, the thing is, the .png is a replacement for the .rsr in ProPack. If you install something using an .rsr, PPP creates a .png and ignores the .rsr after you load it the first time. You can just delete the .rsr. And for new stuff you save, it just makes a .png, so you see, PPP user's CAN'T really make .rsr's. Sorry, I'm afraid they're becoming antiques, now ;)
