I have a mac os preference pane that i'm developing at the moment and I'm finding it's behaving differently to what i'm used to when it comes to installing. When I double click on it to install it instead of receiving the option to install it for this user or all users I am just asked whether I would like to install it and this is performed for all users. Something else i've noticed is when I then double click on it again to reinstall instead of being given the standard prompt to replace I receive an error saying that the prefpane is installed with Mac OS X and can't be replaced. It seems like it might be getting incorrectly identified somehow or maybe i've set something incorrectly.
Any help would be appreciated.
