I have just got the error Maxima encountered a Lisp error: Type-error in KERNEL::OBJECT-NOT-LIST-ERROR-HANDLER: |&STYLE,[POINTS,4,3,3]| is not of type LIST Automatically continuing. To reenable the Lisp debugger set *debugger-hook* to nil. I cannot find any commaand in wxmaxima to do that I have tried debugger-hook:nil but no avail Any hints? thank you Pol
