Boxwood leaves turning brown

[femlow]

I was recently given a variegated boxwood bonsai but within a week the leaves started turning brown and many are falling off. It has quickly degraded and I am afraid of loosing it entirely.

It shows no signs of bugs.
I've made sure its well watered.
I moved it to a cooler area, and in both places it had mostly indirect sunlight but quite a bit of light.
It hasn't been excessively fertilized.

I don't know why its fairing so poorly. The only thing I can think of is if there was root damage when it was transplated shortly before I got it, but the person who did it is experienced and that doesnt seem likely.

Any ideas? Whats causing it? What can I do? Any help would be greatly appreciated.

Even the masters have killed trees. It is a possibilty that ,that might have occured., with the transplanting. Also to consdier was it grown indoors originally it may not take well or adjust to the weather.

if its anything like a ficus, it may just be dropping leaves because the schedule of watering and location of the tree was changed...id stick with it a while...
