This article only applies to computers running Windows Vista (not Home Basic) and those with Tablet PC functionality.

Most people are right handed, and menu’s opening on the right hand side where they normally do can be difficult to work with. This artlicle shows how you can get the messages and menus to open and appear to the left of your hand (or vice versa if appropriate) to make viewing easier.

1.  Go to  Start then Control Panel.
2. Click Tablet PC Settings (in category view and classic view).
3. In the General tab, select either as appropriate:
   Right handed - for right handed people, and menu’s will appear to the left of your hand on-screen.
   Left handed - for left handed people, and menu’s will appear to the right of your hand on-screen.
4. Click Apply, OK and you’re all done.
