Since I had Windows 10 installed on my computer, the clone stamp tool is not working properly. It gives me an error message that alt is not working and could not recognize the source point. I keep resetting the clone tool and changing. See attached images. I keep changing the 'Clone Source'. When it works for a few clicks, the clone stamp source has a mind of its own. It is not sourcing from the spot I select. This never happened to me when I was using Windows 7. I've had Windows 10 for a couple of months. Can you please help me? I'm pulling my hair out! thanks.
PS. I've also contacted Wacom. They sent me a link to uninstall the SW and reinstall it. Still having this problem.
