MacBook – OS stops receiving left (primary) mouse click

macbook promousesnow leopard

I've got a frustrating problem that seems to have cropped up within the last two months or so.

Infrequently, the left (primary) click stops registering with the OS, so I can't really click on anything. My mouse moves around the screen, I can right (secondary) click, but I just can't perform a primary click.

I'm running 10.6.8 on an Early 2011 MacBook Pro (http://support.apple.com/kb/SP619). The click stops registering both on the trackpad and my Magic Mouse.

A restart solves the problem.

Any ideas?

  • Double check that you don't have any stuck keys on your keyboard by testing all the keys, particularly the modifiers (shift, option, etc).
  • Make sure there aren't any wizards, alerts, or dialogs hidden behind existing windows or in other spaces (this one gets me often, especially running the odd mix of programs I use daily).
