Many thanks to one our loyal users who pointed out that the GuessMyOS plug-in didn't offer support for the alarm badges (error and warning). Well it does now! Version 0.1.4 was just released and it offers support for the alarm badges for Windows, Sun Solaris, Linux, BSD, and Novell Netware.
Just a quick note, I updated the GuessMyOS plug-in so that it now supports styling Sun Solaris guest operating systems. You can download the latest version here .
