Can't paste (Command+V) into an NSTextField

I fixed it by linking the "Paste" button in my NSMenu Main Menu to the First Responder's paste: command.

What happens when you select "Edit > Paste" from your application's main menu?

Did you:

• Assign a key equivalent to any of your controls (NSButtons, NSMenuItems, ...) that are responding before the Main Menu

-- or --

• Delete the whole Menu
• the Edit NSMenuItem
• the Paste NSMenuItem The "Paste" Shortcut is a key equivalent of the "Paste" NSMenuItem
