Unable to use fingertip in signature box since last update

[BluEydRebelGirl]

Since Windows updated last week, I am now unable to use my fingertip to sign in a document signature box. When I go to sign, there is an outline of my signature but all that appears is a dot and nothing is regognized by the system. I have cleaned the screen, disabled and enabled , componet tested, compatibility tested, calibrated and reset and restored but nothing has worked. I sign documents multiple times a day and using my fingertip was the only way my signature matched my signature on file. My desktop is an ALL in One HP
