When Microsoft launches Windows 8 Release Preview next month the operating system will have improved navigation features for users who like more than one monitor to display all their applications.

The upgrade - the last major tune-up expected before the final version launches sometime this fall - addresses task bars, desktop backgrounds and that no man's land, the common edge shared by adjacent screens, according to the Building Windows 8 blog.

The current problem with that common edge is that when users mouse over to them - for example to hit the minimize button - they sometimes overshoot and wind up on the next screen instead of the screen they started off on. They either have to slow down or adjust the window size so there's a buffer between the edge of the window and the edge of the screen.

With Windows 8 Release Preview, Microsoft has created interface corners that are larger than 6 pixels tall so users can pull up a little short of the edge but still hit the active interface. The active area extends a little beyond the corner itself to present a larger target.

These corners have new uses with Windows 8 that they didn't have with Windows 7. Corners contain access to applications, charm bars and the Start screen.
