I have a Sony laptop that I just upgraded to Windows 10 from Windows 8.1. It has a touch screen. Since upgrading a cursor pops up in the middle of the screen every so often & causes the mouse cursor to blink erratically. I discovered that the cursor that popped up had to do with the touch screen. When it popped up, I could move it across the screen with my finger, it would disappear, & the mouse cursor would function normally. It functioned quite well in Windows 8.1 & I never had this problem with it.
I have since turned off the touch screen to eliminate the problem but would like to have it functioning since I do occasionally use it. But having to deal with it when it pops up is quite annoying.
Has anyone else had this problem & discovered how to fix it? Or does anyone have any suggestions on it?
