Thanks guys for the input.I am still at a loss to the problem,as an example, when I move my mouse arrow/pointer an object like one or all of the notepads or similar item on this [ click here ] or any other site, then it leave the squared box with the title 'Mark'on the object, even when I have moved the pointer to another area on the screen.I do not press/click-on any buttons on the mouse.
This phantom icon leaves it trace on the objects the pointer as touched, and cannot be removed. I can leave the particular website [with icon intact] and return later when the icon as dissappeared, only to return when I point to the item. The icon only appears on objects like product pictures, and not on wording.
All sounds a little weird, but there must be an answer out there.
