If you just have a few FLAC files, convert to ALAC. If you have a lot of FLAC files, the solution is to ditch iTunes and use another music player.
 
Such as? I’ve been recommended Foobar and nPlayer

I'd recommend Swinsian, it's not free but for me, with a very large music library, it's the best music player. It plays all the formats, no problem at all and excellent sound. Free trial version and then just 24.95$.
