My HP specter laptop has an issue when using the touchpad or a external mouse. Whenever the cursor moves over an executable portion of what's on the screen like a button, etc, the screen goes black until you move it away from that executable spot. This does not happen with the touch screen. It was not always this way and I have tried updating drivers. I have tried the external mouse while that touchpad is turned off, all to no avail. Occasionally it will work correctly for a while and then start doing it again out of the blue. Any help would be appreciated
