Spontaneous un-programming of Arduino USB board

Hi Daniel and All:

  1. Thanks for the additional reference.

  2. I am now having trouble reliably reproducing the problem. After that first (I thought) successful replication of it, I have cycled the input power for over 16 hours at different frequencies and not corrupted the memory.

  3. So, until I can reliably replicate the problem, "fixing" it will not be detectable as such....

  4. In conclusion, I may be out of touch for an extended period until I learn more.
