This started about 2 weeks ago. When I try to start Jedit I get the following errors: Exception in thread "main" java.awt.HeadlessException at sun.awt.HeadlessToolkit.getScreenSize(HeadlessToolkit.java:279) at org.gjt.sp.jedit.gui.SplashScreen.(SplashScreen.java:57) at org.gjt.sp.jedit.GUIUtilities.showSplashScreen(GUIUtilities.java:1844) at org.gjt.sp.jedit.jEdit.main(jEdit.java:330) I am not able to launch Jedit from the menu entry, as I think it is doing the same thing. When I try to launch from command line, this is what I get. I am just typing "jedit" and pressing enter. Also, I can open Nautilus, navigate to jedit, right click and choose "Open with sun java 6 runtime" and it works fine. Should I be using any command line switches? thanks for any help or suggestions.
