I like to have a different login background than the stock one, and I had no problems with it previously. I think, though, since the 10.6.6 update I've had problems with it. I tried using MacPilot like I have in the past, and that didn't work. I tried going into the CoreServices folder like I had in the past, and that told me I didn't have permission to change such files (even though I'm an Admin user on this account). Anyone else having problems with this same issue?
