FM does not write Device Configuration on 89LPC935

[mform]

I am using an 89LPC935 in a new circuit and using Flash Magic. I try and clear the checkbox to enable the RESET pin (that is, I don't want to use RESET) in the device configuration. I get a message box saying that the device was re-programmed correctly, but when I read the Device Configuration again, the enable RESET box is still checked. I have used FM many times and this is puzzling. Does anyone have an idea on what is going on?

Thanks.

Mike
