I recently downloaded and burned a core-current iso and booted to it do do a grub install but found that the "ab <extension>" syntax no longer seemed to do anything. I tried "ab grub" and "ab grub-0.97-splash.tcz" and just got some kind of message saying that it doesn't know what "ab" means. OTOH tce-load worked perfectly. Has the application browser been removed from the 'core' version or has it just been renamed to something else?
