I'm having issues with my mouse. It's not a continuous issue but it's persistent. When I go to sign into my user account the cursor is already clicking on the password section. When I finally get signed in and move the mouse to click on an icon, it drags across the screen, highlighting as it goes along. Left clicking seems to make it go away for a minute but it will continue for a while and stop. I have run MBAM and AVG and I haven't found any issues there. I have also switched out my mouse and used a different usb port to make sure that it wasn't either of those. Windows is completely updated and I've checked to make sure that the drivers for the mouse are current. Any suggestions?
