Dan,

you'll have recover the scripts from the droplets and use the current
'D&D Tclets' app to create new ones to get them to work with a
different major Tcl/Tk release (and potentially minor release) than
what you originally used to create them. This is a limitation of the
way the droplets are implemented (i.e. by embedding the scripts in a
copy of Wish which is linked against the tcl and tk shared libs)

the scripts are stored in a 'TEXT' resource named "tclshrc" in the
droplet, use ResEdit, Resorcerer or similar to extract them, or write a
tcl script to do so... (using the resource command)

if you only want to update the droplets, you can either paste the TEXT
resource in a copy of the current Wish or copy&replace all resources
from the current Wish into your old droplet (more risky, be sure no
resources from the old wish stay around after the operation)

FYI, this is the tcl code 'D&D Tclets' uses to write the resource (it
is itself a droplet BTW)

    file copy $stub $target
    set id [open $tclFile r]
    set rid [resource open $target w]
    resource write -name tclshrc -file $rid TEXT [read $id]
    resource close $rid
    close $id

Cheers,

Daniel
