I use Geany on Linux but I think it runs on windoze as well.
If you only need syntax highlighting & code completion, what didn't work with the other editors?
That's what i was wondering as well. If all you want is editing, then there are many programming editors available, many for free. My favorite free programmers editor:http://www.crimsoneditor.com/
As for compiling and uploading, how do you do that? Run make fromt eh command line?
I wish there was a source level debugger! That would be awesome.
