Manage to melt (3)
I believe the answer is:
run
This clue is a double definition.
'manage' is the first definition.
(both can mean to organise)
'melt' is the second definition.
(I know that melt can be written as run)
'to' is the link.
(Other definitions for run that I've seen before include "escape" , "Flow quickly" , "Dart" , "Uninterrupted sequence" , "publish" .)
