AHK_L tray code to clear orphaned icons that actually seems to work

[MilesAhead]

This is not my code. The author has generously granted permission to distribute the utility with your programs. If your app is written in AHK_L then you could just include the function. For apps implemented in other languages, compile as a stand-alone exe and run the exe when you wish to clear the task tray of dead icons.

As one example, I wrote a hack for my own use that launches Giganews accelerator, then runs my Newsreader and waits.  When I close the Newsreader app, it kills Giganews, then runs the orphan killer app to clear the GA icon from the tray.

Thanks, MilesAhead.
I had some code to do this under XP but it broke with W7. As a stop-gap measure I've been running the mouse around under program control in order to clean up

This is the 3rd solution I've tried that I can remember.  The first 2 seemed to work about 1/2 the time. This one looks more promising.

Didn't work for me on a first, quick try. 
I'll take another look later…

You have to compile from the source.  The attachment posted by the author with no compression or icon didn't work for me at all.

I made a small mod for calling it as a function that sets DetectHiddenWindows On, then restores the original state at the end of the function. For AHK_L apps you can just include the file and call the function.
