Thanks for the swift reply.

I have since tried the programme on a completely different PC with latest Win XP etc and Java etc. Good graphics card and updated drivers.

The same problem - when I try to print, print preview or export to PDF the program shuts down. Although this time no error ...

Fantastic programme, but cant export or print

When I try to print preview or print to PDF i get an error in Java 3D window

Failed to create reference rasterizer 3D device -D3DERR_NOTAVAILABLE

Then the program exits

I am running a 256mb laptop with WinXP
I have the latest Java 6.2 ...
