Hover Click Problems

Hello All, my first post.
Am running Ubuntu Mate on Dell Inspiron Laptop.
Mate is going well and I have all updates installed.
Hover Click is driving me mad instantly opening everything the pointer goes anywhere near !
When I google the problem all I can find us go into OnBoard/ Preferences/Universal Access and then turn off or play with Hover Click Settings.
BUT on my Universal Access pop up Hover Click is greyed out showing 0.00 delay and I cannot change this.
Can anyone advise please ?

Problem fixed.
