After I have used the computer for a while, my mouse changes behaviour. It requires that I do another click to deactivate whatever action it was doing.
For instance, when scrolling down a directory of photos, if I don't click before moving the cursor from the scroll bar to the photo icons, it will highlight all the photos it passes over...
Same kind of behaviour when I clone part of a photo in Photoscape. If I don't click after finishing the cloning, the cursor will hang on to the cloning brush and drag the cloning over everything it goes over, even the function buttons (undo, redo..) at the bottom of the screen.
Is there a way to avoid this?
My computer is a Lenovo ThinkPad T520 with Windows7. Thank for for any input regarding this issue.
