This is slightly OT as it's about setting up AC3D .. but the error I'm getting is a library error.... Error-start ac3d: error while loading shared libraries: libstdc++-libc6.2-2.so.3: cannot open shared object file: No such file or directory Error-end ..despite the fact that I've installed the 'libstdc++' pack using synaptic. Anyone got any suggestions as to why this should be... (probably something obvious... but not to me I'm afraid) Ian
