Mouse does now work to activate tabs, links etc below full screen

In the last few days I can only action any tabs, links etc when I maximise my screen. If my screen is even only slightly smaller than full screen mode I cannot activate anything with the mouse - all tabs, links etc just don't work! Not sure what's triggered this change as have not done any recent upgrades.

Safe Boot, (holding Shift key down at startup), does the problem occur in Safe Mode? Could take 10 minutes.


Safe mode attempts to repair Disks & clears lots of caches & loads safe Drivers, & prevents loading of 3rd party extensions, so if Safe Mode works try again in regular boot.


To find out if it's system wide or user specific, try this...


Open System Preferences>Users & Groups, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.


Does it work in the new account?
