The problem is not Naviter's, the OpenGL in VMware Fusion is simply broken. In fact the bugs they have are easy to reproduce with standard GLScene demos for the GLScene 3D graphics library that SeeYou uses, I've done that and provided to VMware years ago (literally). They clearly don't care about OpenGL support. You can try Parallels to see if there OpenGL support is any better. Otherwise bootcamp and booting into Windows will work.

At some level it is unfortunate that Naviter uses OpenGL on Windows, but hey a long time ago it probably seemed a great idea. OTOH it would makes it a bit easier for them to do a native OS X port :-)
