I've been following this forum for some time and learning a lot from all of you! 

I have a problem with in-circuit programming using the SX-KEY (USB powered) in a 3 volt circuit.  Programming always works, but unless I unplug the SX-KEY from the circuit the program never runs.  Alternatively, I can go into the DEVICE settings, turn off Crystal Drive and program again and it all works fine with the SX_KEY still connected to the circuit.

I'm sure that I'm just not understanding some basic function of the IDE.  I don't want to use the debug functions and for most of my circuits and I typically use the following settings in SX/B:

DEVICE          SX28, OSC1MHz, TURBO, STACKX, OPTIONX
FREQ            1_000_000

(Yes, I'm using a SX28 chip and I want to use the internal oscillator at 1MhZ.)

I'm running version 3.3.0 of the IDE and 2.00.30 of SX/B.  I don't recall having this problem some time ago with earlier versions of both the IDE and SX/B.  Did something change?

Thanks,
Katie
