"Calculate duration upon adding files" is checked, and it was checked, but I still have to calculate it manually, by pressing "calculate duration"....
Also, I still have two tabs, and it is not installed twice, one is "RadioBoss" an the other is RadioBoss Standard (5.6.2.0). The other one shows up when I change any of settings...., and it stays there untill I restart computer.
And, one more thing, where can I find "Remove nonexistent files", now there is only "Show..."?
