Express difficulty finding temporary solution (5,3)
I believe the answer is:
quick fix
'temporary solution' is the definition.
(I've seen this in another clue)
'express difficulty' is the wordplay.
'express' becomes 'quick' (as in an express train).
'difficulty' becomes 'fix' (fix is a kind of difficulty).
'quick'+'fix'='QUICK-FIX'
'finding' is the link.
(Other definitions for quick fix that I've seen before include "Expedient" , "temporary solution" , "no lasting cure" .)
