Hi evyone,
i'd like to install and use the background visual plugin (link: http://plugins.jedit.org/plugins/?Background)
It's not working, i dont know why.

I installed it form the Plugin Manager inside jEdit (version 4.2 final).
Now I can find the background item in the Plugins Menu.
The item looks chacked, but if i click on it i get this error message:
