Decided to try this today...
1st: +1 for keeping the INI in the same folder as the script, for portability.
2nd: AVG reports "Virus Identified Worm/Autoit.LM" - I am sure that this is a false positive, but it would be rather nice if this didn't happen!
3rd: Seems very fast - thanks very much for sharing the script
UPDATE...
I compiled your script on my own machine, with the latest version of AHK, and AVG now likes the EXE!
4th: How about a nice icon for the tray? (Ampa doesn't like the default green H!)
