Background app in OSX.3?

[Brian Yennie]

My understanding is that you need to set _ LSUIelement_, and then also 
"touch" the application and/or move it in and out of the Applications 
folder. This should work like the "Dockless" application mentioned 
before, except that sometime around Panther the OS started caching this 
information and so you have to force it to recognize your change.
