Thanks Darrel,

After I posted my message, I added a blinky and noticed the "very slow motion".

Now I use a 20MHz crystal so I corrected the configuration fuse and added the DEFINE information.

But new problems come up...

To get the program starting, I need to approach my finger close to the xtal (?!) - it looks like some capacitance issue. I added a 10Mohms resistor in parallel with the xtal and now, the program starts everytime I power the PIC.

On the other hand, my PICKit2 programmer won't recognize my PIC when I have a 20MHz xtal intalled on the breadboard. I don't know what this comes from. Maybe one of you does?
