Hello,

This is a known bug. Download draw.lisp and grcommon.lisp from here:

http://maxima.git.sourceforge.net/git/gitweb.cgi?p=maxima/maxima;a=blob_plain;f=share/draw/draw.lisp

http://maxima.git.sourceforge.net/git/gitweb.cgi?p=maxima/maxima;a=blob_plain;f=share/draw/grcommon.lisp

and place them in your local share/draw folder.

That should fix your problems with wxdraw.
