    I have a /bin/csh script which CRPs onto another node to run a program
    which is only licensed for that node.  If I type ahead of the display
    manager input window, the typeahead is somehow thrown away.  This is
    painful as I'd like to stack a bunch of calls to this script to be
    executed one after the other (they take a while to run).

CRP redirects all four standard streams to the remote process.
Hence your typeahead is being sent along, though your program isn't using it.

    Can anyone explain why this happens, and if it can be fixed?
    ...
    crp "/com/converter -args" -on //node -me -cp -nwp -n progname

The easiest fix is to redirect standard input from /dev/null:

    crp "/com/converter -args" -on //node -me -cp -nwp -n progname < /dev/null
