Mouse works in that the mouse cursor moves around on screen, but I cannot click on anything. This is true both with the Bluetooth trackpad and a mouse connect directly via USB. I have tried cycle the machine off, but still the issue persists.
Try resetting the SMC and PRAM.
Thanks for the response Barry, but I do not know what SMC or PRAM is (are). Any additional info would be helpful.
SMC=system management controller reset like this: http://support.apple.com/kb/HT3964
PRAM=parameter random access memory reset like this: http://support.apple.com/kb/PH11243
