Hi Joe,
Someone else reported this after the 2.3.9.3 release. To solve it I've removed the Artisteer specific selectors from the adminmenu/style.css file so it looks like this:
div.mojo-tabs ul > li::before,
div.adminmenu ul.simplelist > li::before {
content: ''; display:block;}
but then I found some places where the Artisteer bullets were happening in places where I don't want them, so I added this to the style-artisteeroverrides.css in the Artisteer skins:
ul.simplelist > li::before,
div.gallerymodule ul > li::before,
ul.simplehorizontalmenu > li::before,
ul.blognav > li::before
{ content: ''; display:block;}
I also updated our Artisteer 4 skin exporter plugin so this is included when exporting from the latest version of the plugin.
Hope that helps,
Joe
