[Stuff deleted]
We have expericened this problem too after installing IDL 3.6.1
I've talked to the tech people at IDL, and they are aware of the problem.
They admitted that it was a bug, (in not so many words ;-) and are working
on fixing it. They suggested that I copy map_set from our previous version,
and use it as a substitute. I did this, at it solved my problem.
