Is there any way using the newer MPLAB/Picstart Pro's to 1. program chip with protect off 2. Verify the chip 3. turn on the protect The newer versions don't seem to allow options to just set the protect fuse (#3) without potentially trying to re-porgram the chip again, whereas I seem to recall the older (2-4 years ago) did.
