the fix works but it breaks this little thing on both skins (the scroll thing in the playlist), now this is super small so its not important but maybe its also easy to fix?
It's not possible to change the size of the scrollbars in WasabiXML v1.3x skins, only their colours. This is how you can do that for MSDZero skin:
1. Copy the attached scrollbars.png into the window folder of the skin.
2. Remove all the studio.scrollbar.* definitions from system-elements.xml.
3. Paste the following wasabi.scrollbar.* definitions into system-elements.xml:
