otay here's my specs if it will help.... 400mz PII, 64mb RAM, 2 15 GB HD, running Win 98 (original PC edition) on the C drive & Poser 4 (with the latest patch installed) on the D drive. The problem occurs with any incarnation of the skirt, (post fix) I even tried with a scene containing 4 Vickies... 3 had the old skirt, 1 had the fixed version. All of the old ones morphed (with the shear of course), the new one just sort of sat there & laughed evilly :-)
