All works fine now!

The problem was I was not unchecking the "Enable debug mode" box in the ICD
options window, as Wilfried suggested. I simply unchecked the "Compile for
MPLAB-ICD" box in the Project options (HiTechC compiler), and forgot the ICD
window. I knew I should do it, and I've done it in the past, but my memory
failed (once again)...

Thanks Wouter and Wilfried for your time.

Alvaro Deibe.
