#6 Win version does not export sticks to VRML

[Clive Norton]

When exporting stick models to VRML, a file with only a header is generated (about 250bytes)
When exporting ball and stick models to VRML, a file with header and with all the balls are generated as spheres, but the sticks are absent.
When exporting spacefill models, all the balls are present as spheres.
When exporting any of stick, ball and stick, or spacefill to POVray, all the balls and sticks are present as spheres and cylinders, and the model renders correctly.
I am using Win XP32 OS.
I have tried RasMol 2.7.5 (09 Aug 09) and all earlier versions backwards until the VRML export feature no longer appeared. The symptoms are the same in all versions.
