Aduino program development environment

I ask what development environment do users find effective in a MS windows structure?

The standard program works well for me, but has no auto-save function so it is very limiting when I have poor windows system reliability (thanks Microsoft) and poor hardware availability (thanks to my less than ideal power supply - thanks Oxxx Energy).

What program editor (as an alternative to Arduino 1.0.5-r2) do others use? I'd obviously prefer to have at least some auto-save function, and ideally some editor recognition of language syntax.

Thanks

The other one used a lot is Atmel AVR Studio. It's free. You have to install some plug ins to program Arduino on it but there is plenty of tutorial for programming Arduino with AVR Studio. It has sintax recognition. Auto save maybe, I don't know but you can research.

Regards.

Thanks. I'll give that a try.
