If you are the 1% of people that always wanted to run a program / batch file / autohotkey script when the contents of a file/script/text document/htm/css file changes, and you haven't found a program for it, then you might benefit of the program i've put together today:
On Change Run Task.
OCRT is the smallest program that would still be useful for me that I could write using Visual Studio C# 2010 Express. (as it is my first one) I hope you find it useful.
Thanks to kyrathaba for making the tutorials that finally got me started

Possible use cases:
* run your build batch file to compile and create a installation package whenever your auto hotkey script is updated. (reason why I made this)
* run a script to refresh your browser whenever your CSS changes.
* 1000 possible other obscure uses.
Future development will depend on my continued use and any interest from you. I managed to disable ClickOnce but it still requires
.NET Framework 4 Client Profile, which you probably have already installed.
