It loads and runs fine when loaded from the built-in Morphic USB connector via DS2232H pin B, using the FTDI DX call from AplX :
FTStatus ← FT_ProgramMorphICDevice Hndl FileName

You mean 'port B'. Ok, so we know the FPGA works.

I then wanted to test the USB Blaster was working, so tried loading the program that way.
I used JTAG mode - would that be correct for this method ?
It appears to load (Quartus reports OK, Init_Done LED goes on), but blinky LED stays off.
Any thoughts ?

So you've got a USB-Blaster connected to the JTAG header on the Morph-IC-II board? And you know the USB-Blaster works?
Do you have the Morph-IC-II schematic? Can you probe the CONF_DONE, nSTATUS, CONFIGn, etc pins? Actually, if the FT2232 is using passive serial mode, then you can read the state of those pins via the Morph-IC-II Port B interface (since the programming interface needs to access these signals). If CONF_DONE is not high after you load the FPGA via the USB-Blaster, then it indicates a problem with the JTAG interface.
