At work I am currently using SweptAway ( found at lifehacker http://lifehacker.com/software/downloads/lifehacker-code-swept-away-windows-255055.php ), a program that automatically minimizes all windows that are not used for a specific time eg. 5mins.
I find your app quite interesting in that it uses the system tray and it's on demand. I will be using it at home since my distractions are far less and since it uses a unique shortcut ( I use a flood of shortcuts and this one is definitely not taken..). Good job on a great idea and a solid build ( no obvious hick ups, works as advertised).

I've recompiled the ahk script with Autohotkey Version 1.0.46.15 and all is back to normal ( no AVG complaints  ).

If only I knew this a couple of years ago..
I've had to create a set of batch scripts that one would copy folder names on a text file and then have another one read it  as parameters for a "for every - in - do" mkdir command. argghhhh.. Oh, well now I know, thanks Skrommel for the tip..
