After starting wxMaxima it displays "Maxima started. Waiting for connection..." indefinitely in the status bar area. When trying to evaluate cells then "Not connected to Maxima!" error is displayed. After trying to restart wxMaxima several times, there are also several cmd.exe processes left which have to be killed manually.
I've tried disabling ZoneAlarm and Windows Firewall, choosing proper settings or even disabling DEP feature as described on
however no luck with that.
OS: Windows XP SP3
firewall: ZoneAlarm Free 9.2.057.000
Maxima version: 5.21.1
