To the developers,
As the ATmega323 has a JTAG interface why is it not supported under the JTAG ICE catagory in Studio 4?
I have found it is possible to cheat by selecting the ATmega32, the JTAG ICE then complains and gives me the option to select the correct part after which it all, apparently, loads ok.
Also one minor bug, whilst the ICE is accessing the uC the cursor should change to an hour glass, it currently shows "I".
Of slightly more concern, I have found that trying to disable a breakpoint using the F9 key sometimes gives an error message. It can, usually, be cleared by using the toolbar button, after which the breakpoint can be reset and cleared using the F9 key.
