What kind of bug are u talking about?
I lock my desktop too, using the one embedded in the screensaver.
I just type my password and it unlocks.
i had strange issues with the one of e17, so i don't use it.
To fix your ibox give this command:
elive-skel upgrade .e
this will move your old config to .e.old and make a new config in .e
Assa
