My desktop icon wont open. Apparently the file got switched somehow from a folder to a package. I can acess the contents by opening package contents but can no longer click on the sidebar icon to get a list of my folders. Also I can no longer move the files on my desktop screen around to where I want them. I have checked all the settings and none seem to be the problem. Can anyone help. One moment everything was working fine and the next, disaster. The only thing I have done recently is purchase MYPCBackup and been backing up my system.
