I used the incremental patch on my system. It is a windows 2000 system with an AMD Athlon 1700 Chip and 512 MBs of Ram as well as more than 20 GB of empty harddrive space. To describe what is happening exactly: The object does rotate, but it rotates faster and further than it should. It rotates about 1.5 times further than is is supposed to. When the rotation is typed in via keyboard, the object falls apart. The problem seems to be similar to the problem with 3DS-Files we had with the first version of Vue 4. Joerg
