Well, that might be a problem. But in ponyprog, I always perform a write
without an erase cycle, and I never get a verification error. Nevertheless,
I'll try to make the programmer again and try by tomorrow. By the way, I was
using the programmer constructed on a breadboard. Is it necessary to
construct the circuit on PCB? (Here is a 
picture  of my programmer.
