Feeling Noobish with 12F683

[picster]

Ok, this is getting to me.

very simple test program:

CMCON0=7 '00000111 - comparator pins configured as I/O
ANSEL=0 'all I/O is digital
OSCCON=96 'internal 4mhz clock 01100000
TRISIO=40 '101000

led var GPIO.4

CLEAR

start:

led=1
pause 500
led=0
pause 500
goto start

compiles fine (no duh)

Using pbp 2.46, the parallel EPIC PLUS programmer, ICSP harness... erases fine, confirmed blank.

I get a "code programming error at 0000"

Upon "verify", it shows the following message:

"Configuration verify error at 0000. 0FFF should be 00F4. Continue verifying?"
The rest verifies ok if I click YES.

I have verified that I can program a 16F88 right afterwards, with no issues.

What the heck ?

Any suggestions?
