Question re-posting mouse question

Ok so maybe somebody knows how to stop the following from happening.....

When i use my lenovo ideapad laptop for anything i have to be watching where the mouse pointer is all the time , if the pointer hovers over ANYTHING that could be opened by clicking it opens by itself so the only way to stop this happening is to constantly watch where i leave the mouse pointer.

Mr google says this is the answer , go to control panel/ease of access , under make mouse easier to use section it says untick the box that says ... untick the box that says " activate a window by hovering over it with the mouse"

SO this is my problem ........ The box is already unticked !
