I think you misunderstood my post above (I should have written 'on my PC's harddisk' ). I was using the latest wLE (the one in your post) when I reported the problem. The version from 9 june is the version I used today to test if it has the same problem but in fact that one does launch those ELFs. Anyways I did some more testing and tried more ELFs today and actually most ELFs do start with the latest wLE. Examples that don't start are uLE442evil, uLE442d, padtest, geotron (hangs on boot screen). Edit: Just to be sure I downloaded wLE from the link above (which is actually the same one which came with FMCB v1.962 as clearly stated in my first post in this thread) and it goes to a black screen with the above ELFs, except for Geotron that hangs on the boot screen.
