You always have to restart the IDE. I haven't used that method either, but I'm sure it's OK and not restarting the IDE is more likely to be the problem.
OK. This implies the library is in the wrong place. Check that it in the right place. i.e. with all the other libraries.
I might add that I had some grief with libraries using IDE v1.6. I gave up trying to fix it, and upgraded to v1.5. I'm not aware of anybody else having that problem.
