Hi, I'm trying to replace the default Mail icon with a Royal Mail stamp icon which is in a .icns format after I converted it using a program called Img2icns. I read on a Apple help page on Apple's site (http://support.apple.com/kb/HT2493?viewlocale=en_US) that you can open the 'get info' window of both the application and the Royal Mail icon and copy and paste the Royal Mail icon to the space where the default Mail icon is. However this isn't working. I'm not sure what I'm doing wrong, but if anyone else in the forum has done this before a bit of guidance/advice would be greatly appreciated. Thanks! I thought I'd add a screenshot to show what I mean - http://img697.images...shothelper.png/ I'm following all the instructions OK, but it still doesn't do anything. I have a feeling it might be to do with the size of the stamp icon that I want to replace the default Mail icon with, but I'm not sure.
