Rough agreement; with a fair amount of

<innocence>... : what about attemtpting to approach the (at least current)
ROOT CAUSE(S) albeit likely fairly (even more than patching the outcome)
cumbersome (but in the long run..)... 
</innconcence> ;) 

-- if having bought a car I discover the brakes doesn't really do their job
(in spite of the car, considering other aspects, being (easy|nice) to
drive :), I'd rather (chat|complain) with the vendor, than asking the 
highway provider to patch my way along.. building cotton walls.. ('cause
I wouldn't want my highway provider limit my driving experience in the
case I eventually run into a better performing car..). More subtle highway
speed versus security considerations... neglected, of course :)
