List of known bugs:

No.	Version		OS		Known since	Fixed		Description

1	2.1		Win / Mac	10.11.2008	10.11.2008	When downloading several files, some of them are downloaded more than once while others aren't downloaded at all.
2	2.2.0		Win / Mac	10.11.2008	11.11.2008	Authentication not fully working yet. Windows: file-download not working (--> fix will be available by 11.11.2008). Mac: playing and downloading of files not possible (--> fix will be available in by the end of November 08). 
(2)	2.2.1		Win / Mac	10.11.2008	11.11.2008	Fixed the broken authentication in the windows and Mac version when downloading files. Playing files using authentication in the mac version is now possible, however it may take some time until the player starts. The Phonon backend on Mac OS X (QuickTime) refuses the basic authentication information to be passed in the URL, so the whole file has to be downloaded before passed to the player.
3	2.2.4		Win / Mac	12.11.2008	12.11.2008	After canceling the file download, no new download could be started.
4	2.2.5		Win		12.11.2008	13.11.2008	No sound using Windows. Fixed in version 2.2.7
5	2.2.9		Win		14.11.2008	14.11.2008	IDispatch - errors may cause SoundBox to crash. Fixed, now these errors won't be shown to the user anymore and the track is skipped automatically.
