Looking at your problem of lighting I had to note your using the GeForce3 graphic adapter. Several companies put out versions using this Nvidia chipset. But they differ in their use of drivers. Make sure you go into your driver prefernce setup and insure the settings are correct. This chipset absolutely requires DirectX8 in order to perform properly. Make sure you have Direct X8 installed. This Nvida chipset is the company's first true GPU, using what is known as the vertex shader instruction set. The other problem / advantage with this graphic adapter is its dependence upon the software application's support for its GPU and instuction set. I don't know if Poser supports this level of 3D graphic engine. If it doesn't and you have the adapter set to take advantage of its capabilities then it could very well create problems. For not having that support will force the adapter to default mode those functions. If you were using Win98 your files created there are in FAT32 format. If your Win2K operating system is using the FAT format then all files in FAT regardless of being 32 or 16 will be read properly. If your system is formatted for NTFS then it will read FAT32 files but will not save in that format. Systems formatted in FAT32 which includes almost all the standard desktop systems will not read a file created in NTFS. Only another NTFS system will read it. It is part of NT's security.
