When I run wxMaxima it starts fine. Before I do anything i get the following error massage within the maxima console.

'Message from maxima's stderr stream: execvp(maxima, -r, :lisp (setup-client 4010)) failed with error 2!'

I get the same error when I try to add 1+1.
When I run wxmaxima from the console I get the following two debug notifications.

Debug: Unrecognized accel key 'hoch', accel string ignored.
Debug: Unrecognized accel key 'herunter', accel string ignored.

'hoch' means 'up' and ''herunter' means 'down'

I the end it is not possible to do any calculations.
