PICkit is back

I used the last Reflash procedure you send me (with PC-Loader).
So here are my testings in a little table. I tested one time without ZIF adapter and one time with. 16F1937 seems to have a very strange behavior with/without ZIF ??
One remark also is when programming the 18F4455 The Prg led is not on, do you have an explanation for this ?
