This much I understand, except instead of writing the proxy script myself. I am
having the webserver (Nginx) doing the proxying for me. I redirect /geoserver to 
http://otherbox/geoserver. This effectively "fools" OpenLayers into thinking my
geoserver requests are in a subdirectory, but I'm not writing the proxy. This is
dead standard web server configuration. With proxying implemented on the server,
why would I need ProxyHost set in OpenLayers?

Again, I don't think the problem is a proxy problem (but I am not 100% sure)
because the same server (Ubuntu) serves the same page on the same FF 12.0 on a
different machine (Windows) just fine. The identical page on FF 12.0 on a
Windows client has a clickable map. In addition, a known working page (renders
just fine with a clickable map on Ubuntu 11.04) does not have a clickable map on
Ubuntu 12.04. The only time I have trouble is with FF 12.0 on Ubuntu 12.04
