Error in wMaxima



Hi,

I have tried to find a solution tot this error on the internet, but have not been successful. I am running version 5.38.0 on Mac 10.8.2.

When I put a simple expression in wMaxima and ask it to factor it (or derive it, or integrate it), the system crashes and outputs the following error message several times:

Maxima encountered a Lisp error:
 decoding error on stream
 #<SB-SYS:FD-STREAM for "socket 127.0.0.1:56693, peer: 127.0.0.1:4010"
   {13649991}>
 (:EXTERNAL-FORMAT :ASCII):
   the octet sequence (203) cannot be decoded.
Automatically continuing.
To enable the Lisp debugger set *debugger-hook* to nil.

I had this issue with previous version, and am currently trying it again with latest version (5.28.0), but result is the same.

The same version works fine on a Ubuntu installation.

Thanks for your help,

Marco
