I followed the instructions on your wiki.  I noticed your site pointed to java3d 1.7.0-pre1, which is slightly different than what I had earlier downloaded.   I am still having the same problem, although this time it seems to be extremely slow but less likely to hang completely.  I also get an actual error message, below.  

I am using this with swing, Canvas3D as a heavy-weight AWT component.  I know this is sometimes not recommended, but it worked fine on an earlier Windows 7 and two even more ancient Windows Vista machines.  JCanvas3D, which was a work-in-progress, used to not work.
