Some of my tracks are missing the wave form in the browser, I only noticed this after upgrading to v3. If I right click the track and choose "Analyze Track" the analyses takes place but when finished there is no beat grid and no wave form in the browser "Preview" column, Key is set to "A" for all these tracks.
