I suggest you to download this version of swt: http://www.eclipse.org/downloads/download.php?file=/eclipse/downloads/drops4/R-4.3-201306052000/swt-4.3-gtk-linux-x86.zip
Get the swt.jar from it and replace the swt.jar that comes bundled with Zekr with the new one. It may also be related to using OpenJDK instead of Java. -- You received this message because you are subscribed to the Google Groups "zekr" group.
