Left click intermitent
Left click some times does not work. Try to close a window hit the red X but nutting happens, try many times still no action. If i left click elsewhere on the window then the red X the window may close. Tried 3 different mice, the same on all. Also happens on pull down tabs Safari, and other places.
This happens on both my Mac book pro and my Mac pro, very annoying
Any ideas?
Mac Pro, OS X Yosemite (10.10.2)
