I just installed AVR Studio 4.15 yesterday.
For those who don't know, I use an ATmega2560 with around 145 KBytes of code. When I used to start up debugging in AVR Studio it would take 3 to 4 minutes for the debug window to finally wake up and it took my poor little 1 GHz Xeon to its knees. I'd use the time to read the web (including AVRFreaks :) ).
So, imagine my surprise when the latest version of AVR Studio took only about 15 seconds to wake up!!! :shock: And no muss, no fuss from my workstation! :D
Thank you, AVR Studio team!! You've made me far more productive! (And darn you, now I'm falling behind on my web reading! :twisted:)
