thanks for the report of a true bug in
a lucid and comprehensible way.

i guess nobody cared until now. i'd rather teach
another program to read .dcd or even better use the
molfile plugin library than write files in an impractical,
slow, and low accuracy format.

the required change to the crdplugin source
code is trivial (attached) and will (i hope)
be added to the VMD code and available in the
next beta/release version.
