Michael,

Thanks for explaining "// config: norepeat". I saw that at the top of a few scripts and wondered what it was about. What does this do?
// config: norepeat noautolaunch

I guess "// config: norepeat" should be at the top of every script that can create an alert triggered by a problem encountered by the script.

I'll keep your segmentation violation tip in mind in case I'm ever in that pickle again, but hopefully I'll be able to avoid it with everything else you've shared.

I haven't done anything with pickers or event loops yet, but I'll try out your suggestions.
