Three Thoughts:
See what happens when you hold down the control key, and then click on the icon. Do the you the default right-click menu?
- Create a New Administrator:
Try creating a different administrator, seeing if it then works. If it does, then is it something misconfigured in your current user.
Hold Down the Shift Key upon boot. Once at the login screen, release shift. See if it all now works. In Safe Mode, only necessary items load, preferences are set aside, and corrupted settings (i.e. caches) are fixed. Wait 30 seconds, and then reboot, login in as normal. See if they now open.
