This is my iMac spec: "Core i5" 2.7 27-Inch Aluminum (Mid-2011) is powered by a Quad Core .... matrix displaywith "IPS technology" and a native resolution of 2560x1440, running iOS Sierra 10.12.1
A couple of weeks ago I bought a Wacom Intuos Pro medium graphics tablet and installed the driver.
Since then, my mouse has been all over the place. It slows down, sometimes shoots all over the screen, 'drops' things when I'm trying to drag them. Even when the graphics tablet (wireless) is not switched on.
I unplugged the mouse, switched on the iMac, then plugged the mouse back it when it realised it wasn't, in the hope that it would trigger the mouse to work properly, but no joy.
I realise that the graphics pen is used instead of the mouse, which is fine whilst I'm in Photoshop, but I prefer to use the mouse for other programs.
Any suggestions as to how I can get my mouse back to normal would be gratefully received.
TIA
