the constant reboot bug with certain flags IS NOT FIXED.
And not mentioned under known bugs.
Hey, Sandisk, are you kidding me? There is a german word which is very fitting for your behaviour:
VERARSCHEN
And I haven’t even tried playlists. If you can not fix constant reboots, I am sure you are completely unable to fix a ‘lockup on non-windows-7-generated-playlists’.
