I could have tried this but i do not have a windows system accessible to 
me along with my stk500. So if i just got the older hex file ill burn 
it right here. :-)

Thanks! ill try this its all i need! :-P

I have checked this out. Had a little trouble compiling it on linux with 
the makefile being for windows only. Anyway i got the windows 
executable and ran it under wine. This is good but not exactly what i 
am looking for.

Basically i have no problem using the command line so i am not really 
looking for a simple replacement. I was more looking for a stk500 
dialog that pops out of avrstudio. I just do not want to be going 
through the datasheets of the processors to know which fuse bits to 
program and which not to. This means a lot to me as i do not work with 
the same processor most of the time.
