If I set it's LSUIElement to true, can I still have it show or hide it's window? All I really want is for the app to not have the icon in the dock as you expressed, but I DO want the user to see it when I show it's window. 

Hi Bob,

I'm sorry, I don't know whether the LSUIElement flag would suppress any
windows - I don't think it would, but you'd need to test it.

Manually edit the info.plist file and just add these 2 lines:
    <key>LSUIElement</key>
    <true/>
AFTER the <dict> tag (3rd line or so)
and BEFORE the <key>CFBundleDevelopmentRegion</key> line

Hope that helps.
