wxMaxima-Maxima connection failure



Hello Maxima users and experts,

My first post to the list.
I've searched this mail list and others and I realized that the problem I am about to describe is fairly recurrent in Windows systems, but none of the suggested solutions that I read worked for me (nor for the user posting the message). The problem is that wxMaxima does not connect to Maxima ever, after installation, so nothing gets done. I have tried this in two systems

Problem in System 1.
No firewall. No anti-virus. Windows firewall off.
Windows XP Home Edition version 2002 Service Pack 3
Maxima 5.23.2
wxMaxima 0.8.7
Message after start (on bottom right) : "Maxima started. Waiting for connection ..."
Error Message after any calculation : "Not connected to Maxima!"

Problem in System 2.
Zone Alarm (with permissions for Maxima, wxMaxima, and Tcl/Tk, and also with firewall turned off)
Windows Vista Home Premium Service Pack 2
Maxima 5.23.2
wxMaxima 0.8.7
Message after start (on bottom right) : "Maxima process terminated"
Error Message after any calculation : "Not connected to Maxima!"

The problems persists after giving Maxima and Tcl/Tk permission to avoid DEP.

I tried setting different ports for wxMaxima-Maxima connection and that didn't work either.

I tried installing old Maxima version, from 5.17.1 up, and in all of them the same problem rendered the software totally useless.

I have another Windows XP system at work and there wxMaxima-Maxima work fine (details of that system set up are not available to me now).

So are there any new clues on how to remedy the connection failure?

Alternatively (but not so good), how can I use Maxima directly, without calling it from the Tcl/Tk GUI? (that will no connect to the algebraic engine anyways)

Thanks in advance,

Ruben
