Mouse Lft Clk not working since upgrade to Mountain Lion

Can anyone help please? Yesterday i purchased Mountain Lion, upgrade upgraded my iMac 27, my Air and my old Mac Book Pro, the Air and iMac seem fine but the Mac Book pro is not. I use a Bluetooth mouse ( as the track pad is broken) and while it works fine before Mountain Lion loads when its loaded the "left Click' does not work! I've tried 3 different Mice all the same and as i said if i press Alt at boot the mouse is jut fine running the tools. The track pad is set to be disabled if it senses a mouse and this was working ok in Lion.

Going to restore Lion from a back up but just wondered if I'm alone here.

Harry.

Try going to your system preferences to mouse then click enable right click.

I had left click problem on both the trackpad and a usb attached mouse. It happened erratically over a two week period. The computer passed Apple Hardware Tests at local repair center. Running OS 10.8.6. Tried to reinstall OS, mouse would not click to allow for reinstall, keyboard options not working....Shut down for 2 hours, restarted mouse back. Reinstalled the OS, have now been working for an hour with no repeat of the left click problem. I had earlier done PRAM reset, spoke with Applecare who thought it was a logic board and offered to have a box sent to return to Apple. May still do that. The fact that it happened with both the Trackpad and an external usb Apple mouse makes me think an OS bug might be lurking around.
