I have just done a simple test
All 2313 port B set to output.
do 
Portb=FF
delay 5 seconds
Portb=00
delay 5 seconds
loop

programmed with serial method (AVRPROG)
connected a led to 5v rail and tapped the cathode to each portb pin in turn - all 
worked as they should - with or without the programmer left connected.
