If you write your own AppleScripts, you’ve probably seen an alert box pop up with this message when you try to run your script:

Press Run to run this script, Quit to quit.

<rant>This annoyance calls to mind Microsoft’s ingenious “click Start to shutdown” design motif. I mean, if I launched this script in the first place, why should I have to tell you again?)</rant>

Fix: When you save the script as an app using “Save as…”, look at the save options carefully. Make sure the “Startup screen” checkbox is unchecked before saving.

See? It turns out it was your fault after all.
