We have just released a new version of the skins and plugins that focuses on compatibility with the latest version of cPanel. As you may know, Roundcube under cPanel runs in a special environment that limits some of its functionality: cPanel blocks some sound and image formats, puts Roundcube in an iframe, and removes the header bar from the top of the page. All those restrictions create functionality problems under some browsers. This latest upgrade fixes a number of issues that the skin and plugin had with the user interface. We encourage you to upgrade your Roundcube Plus software if you use your webmail under cPanel.
