Just a quick note to myself and potential users of Yoxos under Ubuntu 12.04, which seems not to work in the default installation.
The problem is that after starting Yoxos Launcher and selecting “Advanced mode”, empty dialog appears and the application hands.
The cause is the missing library for rendering web pages, to put things simple. In previous (pre-11.10 I think) Ubuntu releases probably xulrunner was used to do so, but now that it’s missing from repos, SWT can’t find a library to handle the rendering.
In 12.04 the simplest solution is to install WebKit, as this can also be used by SWT, e.g.:
sudo aptitude install libswt-webkit-gtk-3-jni
