Trying the examples in the main page, the second [diff(cos(x),x)] works well; the first [integrate(1/(1+x^3),x], don't.

4)
Firts time I double click the formula, the program return the following message:
"(%i1) Universal error handler called recursively (:ERROR NIL
                                                  CONDITIONS::CLCS-UNIVERSAL-ERROR-HANDLER
                                                  ""
                                                  "Couldn't protect")
Universal error handler called recursively (:ERROR NIL
                                            CONDITIONS::CLCS-UNIVERSAL-ERROR-HANDLER
                                            "" "Couldn't protect")
Maxima encountered a Lisp error:

 Error in CONDITIONS::CLCS-UNIVERSAL-ERROR-HANDLER [or a callee]: Caught fatal error [memory may be damaged]

Automatically continuing.
To reenable the Lisp debugger set *debugger-hook* to nil."

The second time, an "Error" window appear with the message: "Error sending to Maxima:: can not find channel named "sock7". You may need to Restart".
