I run the Import Tool, and click browse to select a file to import. When I select one of my files, which has a .CSV extension, the full file name is selected without the .CSV extension. Is this a bug?

This looks like it this is a file chooser bug specific to Mac OS X.
The suggested workaround: disable hiding of file extensions in the Finder, as described here –
check off ‘Show All File Extensions’
