Has anybody managed to get their RPI setup working with the Adafruit 16x2 LCD + Piminer python script?...

I've run a sample python script for the LCD and the display and all buttons are working perfectly (which is surprising considering I hadn't soldered anything for a decade before today!), but when I launch "python PiMiner.py &", the display comes on and just sticks on displaying the RPI's IP address... Occasionally after stopping and starting cgminer the display will change to "connecting to cgminer...", but it then just sticks on that indefinitely... None of the buttons respond when it's stuck on the IP address or "connecting" screens.

The default port is definitely listening;

root@RASPBIAN:~# netstat -l
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State
tcp        0      0 *:ssh                   *:*                     LISTEN
tcp        0      0 *:4028                  *:*                     LISTEN


The following lines are in my .conf file;
"api-listen" : true,
"api-mcast-port" : "4028",
"api-port" : "4028",
"api-allow" : "0/0"
