DigitalDreamer :o) It's coz you're DOUBLE CLICKING on the second character or clothes. Double clicking in Poser means REPLACE, not ADD. One of Poser's many quirks :o) - and a mistake we've all made (I often do it myself even after about 3 years with Poser G) When the "same scale" comes up, you know you've done it again L so just click cancel and try again, this time with the double checkmark :o)
