I just installed the latest Flex SDK, and have got that working great…added the C:\Flex\bin to my system path etc, so now i can compile as and mxml files from the command line…

I was wondering though - I prefer to use programs like Notepad++, and its a bit of a hassle having to flick back and forth between that and the cmd line to compile…

Are there any text editors that have syntax-highlighting for AS and MXML, code folding, and possibly even code-completion - with a “build” button so i can easily compile things?

I tried out Flashdevelop, but i cant get its .mxml compiling to work…
