ok, make sure that you deleted also the [b]data.zip[/b] from MediaMonkey install folder, it is leftover from older builds causing issue https://www.ventismedia.com/mantis/view.php?id=17879
that will be fixed in 2406 (by ignoring and deleting data.zip leftover)

Only solution was clean reinstall. Was maybe really nessary (old ini file 223 kb - new ini file 43 kb).

Thank you for the reply!

Left there only the extracted or the zipped variants -- not both.
i.e. having both 'Black Monkey' as folder and 'Back Monkey.zip' as file is causing the duplication

The recommendation is to remove that skins folder and reinstall MediaMonkey. This may be a leftover from earlier installs.

Skins are only in there once I think:

Please check the Skins folder where MediaMonkey is installed. Are the skins only in there once, or multiple times as well?

What's going on?
