For programming fScript on Windows we recommend Programmers Notepad as an excellent IDE. This very lightweight editor supports JavaScript syntax highlighting and auto completion. It can also arrange your .js files in projects, and you can bind launching fscript.exe with your file to a hotkey. And its FREE, so go grab it
I had a little trouble figuring how to config pn, but I found something that works:
In Programmers Notepad:
Tools -> Options -> Tools -> Press ADD tool.
Name: launch fscript
Command: C:\Users\foo\Desktop\fscript\fscript.exe
Folder: C:\Users\foo\Desktop\fscript
Parameters: %d%f
Shortcut: F9
Save: Current file (in case you forget to save the change you did before running)
Now, just open a fscript js file and press your shortcut key!
