Abstract
A first computer workstation 810 is linked to a second computer workstation 820. A window 812 which is displayed at the first computer workstation is copied to a window 822 at the second computer workstation. A hook procedure is used to intercept movement of the cursor 814 at the first workstation. These movements are then transmitted together with a representation of the cursor image over the link from the first computer to the second computer. The cursor image is then displayed 824 at the second terminal in the corresponding position as at the first terminal. The size of the cursor image is scaled so that cursor 824 has the same size relative to window 822 as cursor 814 as to window 812.
