Have bitten the bullet and bought a new PC - HP Pavilion 550-295na, however, already have a wave of problems. One is with an unresponsive mouse when using Publisher (installed Office 365). Have been using Publisher for years but now the mouse is unresponsive - it works, but I cannot easily move, resize photos, etc - the mouse drags slowly and takes forever - there is a lack of control. I use a wireless Logitech mouse - it works fine with everything else, including Powerpoint. Any help appreciated.
