Thanks Guy I appreciate the support. Elecraft Listen to your customers. It is best to be safe and don't play with your computer while updateing your K3 firmwhare. It is only 15 minutes max.

Sorry, Dick Plenty of others have had that "killed it by starting a browser" experience, including myself. It WAS a P4 with memory being stretched by security patches, etc. I now have a PC based on a quad-core Intel I7 920 with 6 gig of almost cache speed 3 channel memory. I don't worry about it now. If you are running a PC with a single core processor and/or limited memory (as in an older PC which you have kept to use for logging programs), better to not tempt fate. PC's and Windows can do strange things when swapping a lot of memory in and out to disk, which could not be blamed on the utility, apparently including overwriting memory in use by the utility. It's Windows blowing the multitasking, not Elecraft. 73, Guy.
