There's apparently a problem with the permissions on the binary - proabably because I just packed it with bzip2, rather than putting it in a zip or tar archive. Try doing: chmod 777 uae The '777' here is an octal number which corresponds to the permissions to change. The digits refer to in sequence the permissions for the file's owner, the file's group and everybody else. Setting all these to '7' will give everybody read, write and execute permission on the file. You can also write this as: chmod a+rwx uae to achieve the same thing. If you do 'man chmod', it'll tell you more about the chmod command. Hope that helps. Cheers, Rich
