FBX Importer's "Apply" Button doesn't work when exiting.

I’m using Unity 3.4 for Windows.

When tweak FBX Importer settings and exit Unity without pushing the “Apply” button on the Inspector, Unity pops up a confirmation dialog (“Unupplied import settings”) before exiting.
But the settings are not saved even if I selected “Apply”.
Isn’t it a bug?

Thanks.
