Has anyone experienced some power-up quirks when using the new Defender cartridge in a 400? Mine usually works fine, but occasionally I just get a blank screen when I close the cartridge door. I am wondering if there is some problem in using 16K cartridges (I believe Defender is one) with the 400's power supply. I took in my 400 for service; they found nothing wrong with it. All my other cartridges work perfectly.
