If you have difficulty using the mouse or a notebook touchpad this tip may be useful: instead of having to move the mouse pointer from one part of the screen to the other when selecting buttons, why not send the pointer to the default button automatically? In Windows XP open Control Panel, then select the Mouse link from within the Printers and Other Hardware link. In the Mouse Properties dialogue, click the Pointer Options tab and tick the box labelled' Automatically move pointer to the default location in a dialog box' and click OK. The same option can be found by choosing Mouse from Vista's control panel then following the same method.
