Strange Mouse Behavior

I do my Photoshop editing with a mouse.  Intermittently, but far too frequently, it behaves as though I have not released the the left mouse button.  If I'm drawing or selecting, and then release the button to move the cursor up to the manu bar, I end up drawing or selecting all the way to the top of the image.  I can usually get control back with a momentary press of the right mouse button. And yes, I have tried another mouse.  I've tried two other mice.  It's possible, of course that this is a Windows issue. But I've never seen this behavior with any other program.
Dell XPS 8910 running Windows 10 Pro, 64 bit.  All Windows and Photoshop updates are current. 
Any ideas?

Thanks.
