Error in `pre-command-hook' (tabs problem)

i just thought i'd click on the tab to change buffer and i got that: (1) (error/warning) Error in `pre-command-hook' (setting hook to nil): (wrong-type-argument unable to bind this type of event #<misc-user-event (eval (buffers-tab-switch-to-buffer "EXSL.java"))>) i have not the faintest clue what it all means, because it actually did change buffer... and i cannot seem to be able to reproduce it either... just thought you might want to know... for the record... -- # Stef Epardaud, # There is no limit to the power of computing ... # Java Defeater # ... except men maybe ? # Earth # Lunatech Research, # Solar System # soon we will quit researching and start finding...
