Re: [Maxima-discuss] plotdf error, was: XMaxima in Maxima 5.40 seems broken in Windows and wxMaxima has issues

[Raymond <ray...@gm...>]

That change worked to eliminate the plot error for me!  But..
Now quit();  (in xmaxima) is giving me a problem.   It seems that maxima 
has been shut down but xmaxima just keeps trolling along.
If nobody else has a problem then ignore this and I will do a complete 
reinstall.
