I have the AVR plugin installed into the C/C++ version of eclipse, and I have been trying to add the usbasp programmer, so I can download straight to a ATmega644p. To add a programmer I tried the following:

Window -> Preferances -> AVR -> AVRDude -> 'Add'.

Once I pressed the 'Add' button, nothing happened, and no other window opened so I could add the programmer.

Any help would be much appreciated!
