Hi! Sometimes, in the middle of working on an application with SLIME (from CVS) and AllegroCL (7.0 beta) AllegroCL looses the ability to load a system with the ",l" shortcut. I usually start my sessions loading the system I'm currently working on and at this point it works fine but after a couple of breaks, backtraces and whatever it ceases to work. I'm afraid I can't provide an easy test case right now cause I'm in the middle of a project but maybe the attached backtrace is enought for the SLIME gurus. Cheers, Edi.
