InsightII help



 Hello,
 I am trying to bind a compound to a nucleobase within an double stranded
 DNA generated under the biopolymer module in InsightII, (the compound
 was generated under a derivative of the AMBER parameter set). Trying to
 manipulate 1 molecule without moving the other has been unsuccessful.
 Trying to create a bond between the 2 molecules also doens't work (using
 the builder module). If anyone can help me out, it would be greatly
 appreciated. This should be easy, shouldn't it?
 Thanks,
 John Cox
