Mouse changes behavior- the mouse requires another l-click to deactivate whatever action it was doing.
For instance, when scrolling down a directory of files, if I don't click before moving the cursor from the scroll bar to the photo icons, it will highlight all the files it passes over.
Same kind of behavior when I mark part of a text: If I don't l-click after finishing marking the text, the cursor will hang on to the marked text and drag it over everything it goes over.
Finally, when making the settings on the Mouse control panel, the speed is selected by moving the arrow on the slow to fast line – move the arrow, stop lift the key and go to Apply Button BUT, when moving to the Apply Button, the arrow on the slow to fast line will continue to move. I have replaced the mouse, removed and replaced the driver and reset all of the mouse settings. Thanks for any help. /Howard
