If anyone out there who, like me, use the Atmel AVR Studio 4.13 to work with JTAG ICE (i.e. using the STK200 or STK500 boards), you will have noticed a problem with fuse bits not being correctly read or set with SP2 of the studio.
Well, thanks to the help of a nice person on the AVR Freaks forum, I now have a fix - a patched stk500.dll. You can get this file by contacting Atmel Support, or if you would like it quicker, drop me an e-mail (warning: no responsibility for what it does accepted etc etc!).
