XStreamity v5.50
Another attempt to fix this plugin skin selection issue.
i.e if you select black skin, save, exit plugin. reboot gui. It should remember the black skin.
If this still doesn't work, with all my messing, I might have messed up your settings file.
In which case do these telnet commands
init 4
sed -i '/^config\.plugins\.XStreamity\./d' /etc/enigma2/settings
init 3
