Brand new MacBook Pro with Retina display - Mail, Preview and App Store freezes on launch I can never use most Apple-made apps on my MacBook Pro with Retina display, as the UI never responds, however Mail gets new emails and Preview displays images. It's just that I cannot click.

I can't close it and I can't use the menu bar, however it responds to keyboard commands.

I have to force quit these apps every single time. I don't have the 'reopen windows' option on, so I don't understand what is going on. Activity Monitor is normal.
Found out what it was.

Ink > Write Anywhere was enabled, when it shouldn't. As soon as it was disabled, the affected Apple apps started working again.

I thought it was something to do with the Wacom tablet I bought, but couldn't find any connection. Now I know it was Apple's own Ink software. Maybe I shall report it as a bug.
