variable definition fails in wxwidget editor

[rolandchee]

to vardef
  make "a 42
  show a
end

When done in the logo terminal, it successfully outputs "42".

However, when done in the wxwidgets editor, it outputs

I don't know how to    a in vardef
[make    a 42]

I notice in the wxwidgets editor the "a becomes “a. Does the error have something to do with this?
