I´m not sure if I´m right here because it seems a problem of skinbuilder but it happens only in the module dhtmlxMenu - so I place it here.
If I create a skin (see attachment) for menu the selected backgroup color is OK, also the shortcut foregroup text but for the normal menutext a wrong color ist.
For unselected menuitem both the shortcut and also the itemtextcolor is wrong.
You can see this directly in the preview in skinbuilder.
I know that I can change it directly in the css but I don´t want to do so because in case of updates it´s a nughtmare to set all changes inside the updated css.
