As discussed in the forum (http://forums.slimdevices.com/showthread.php?t=51144). One of my PCs is in a state where regardless of the player selected in the dropdown (on default web UI) the left hand pane still controls the originally selected player. The right pane does update correctly.

Machine in question is running XP SP2 and FF 3.0.1. Stopping & restarting FF doesn't fix the problem. Bringing up IE7 on the same machine works fine. Other machines on the network (also XP/FF3.0.1) also work fine.

The JS console has a number of warnings (mainly related to CSS errors - 'unknown property "zoom"' is a common one). The only error I see is "Highlighter is undefined" which appears a couple of times (home.html and browsedb.html). 

I'm trying to preserve the affected machine in it's current state for testing....

Server version is:
