ZEPHYRIS  Quick update: Repairing permissions fixed the problem, issue on my end. Works good.  
(Version 2.0.2)

ZEPHYRIS  I set it to run on a Sunday fixed time , shell script never ran rebooted as well prior. Script runs manually just fine.  
(Version 2.0.2)

GRANTNEUFELD  The link to version 1.2.1 downloads a completely different program - Smultron.

The correct link is:

http://downloads.sourceforge.net/lingon/Lingon-1.2.1.zip  
(Version 2.0.1)

ZEITKIND  Version 2.0 immediately crashes on 10.5 (PPC) here.  
(Version 2.0)

ADI2  i get a not available icon on the lingon icon after i unzip the 1.2.1 version. never saw that happen to any app. what could be the problem? it kinda looks like this http://www.flickr.com/photos/lcummings/838409032/  
(Version 1.2.1)

CBX322  Perfect, except one issue:

If using without admin-rights, i.e. just for viewing, it keeps asking for credentials, even if you don't wanna change anything. It should only ask for authentication while editing or writing changes.  
(Version 1.2)

MATTETH  Saved my day. I needed to keep a script alive on a kiosk-type computer - guaranteed, for a long time.

Still works, after six months. If it crashes, it immediately kicks in again, thanks to launchd and Lingon.  
(Version 1.2)

FREDB  Excellent. Thanks for this app.  
(Version 1.2)

GERBER  Wonderful program. Making launchd agents isn't for the faint of heart, but Lingon makes it quick and easy. Lingon even takes a stab at making it intuitive, and succeeds as much as they might, given how complex these launchd files can be.

Lingon also serves as a wonderful interface to control the under-the-hood daemons and agents that make your Mac do what it does.

So far, no crashes, freezes, damaging of my computer (except when I cancelled the loginwindow, but ANYONE could do that!) or anything else. Solid, wonderful, helpful program!  
(Version 1.1.1)

SIMEN  Nothing to complain about. It is the greatest ! I love launchd :)  
(Version 1.1.1)
