Wrong Icon Appears & Copy/Pastes Different Icon
I've had my Blackbook for a couple of months, and all of a sudden today I noticed that a file I created using TextEdit had changed its icon to that of the application PhotoBooth. "Weird" think I, so I attempt to change it back by opening a text file somewhere else on my computer and copying its icon in 'Get Info' and then pasting it into the 'Get Info' of the text file with the weird PhotoBooth icon - except it pastes the wrong icon. Now I have the little house icon that is the same as the user. ***? There doesn't seem to be a way to revert back to the original icon, and now every subsequent text file I create has the little house icon.
I'm wondering if maybe the graphic set for the icons has been corrupted or messed up. How can I get them back to normal? Anyone else experienced this problem?
