Irene,
  There was one small bug fix that DESRES sent us in December 2009 for
the dtrplugin code, that might affect it correctly finding the
"clickme.dtr" file. If you want to try the new version of the plugin
with CatDCD, it is included in the test versions of VMD 1.8.8, which
are posted in the VMD alpha test area on biofs, described here:

Cheers,
  John Stone
