http://www.favessoft.com/downloads.html Trim Work Area is a simple utility that allows you
to trim from the Left, Top,Right and Bottom of
the desktop work area by a number of pixels
using ini file settings. This only effects the area
used when a window is maximized. It doesn't
keep applications from moving into the margin
area.
You may find it useful especially if you use toolbars
that auto hide, or if you have your taskbar set to
auto hide.
Requirements: Windows XP or later.
Tested on a single monitor setup only.
