Table 5-5
Windows XP Visual Effects
Description Causes menus to fade out after you select a command. Disabling this effect makes menus disappear instantly after selecting a command. Causes Windows to display a drop shadow behind menus for a threedimensional effect. Disabling this effect makes menus appear more quickly. Causes Windows to display a drop shadow behind the mouse pointer. Disabling this effect can make the mouse more responsive. Also, some older applications do not work well when this feature is enabled. Draws a filled-in rectangle when selecting multiple items on the desktop instead of just a rectangle outline. Disabling this effect slightly increases the speed with which you can select items. Causes Windows to redraw a window while the window is being moved. Disabling this command makes dragging open windows noticeably faster. Causes combo boxes to slide open instead of simply appear. A combo box is a drop-down list of items that you open from within a dialog box. Disabling this effect makes combo boxes appear more quickly. Causes taskbar buttons to slide to the left when other programs are closed or to the right when new programs are opened. Disabling this effect makes taskbar buttons appear instantly in the new location instead of sliding. Disabling this effect makes taskbar buttons available more quickly when they change locations. Makes screen fonts easier to read, especially at higher resolutions. Disabling this effect increases the speed at which Windows displays windows and dialog boxes. Causes the contents of a list box to scroll smoothly when you click the scroll bar rather than just jump down a few items in the list. Disabling this effect makes scrolling list boxes faster, but often disorienting. Different types of folders in Windows XP can use different background images. Many of the special Windows folders, such as Control Panel, make use of this effect. Causes folders in Windows to display a task pane on the left side of the folder that lists tasks that are related to the files in the folder. Creates a transparency effect on text labels for icons, but this transparency really allows you to see only any other icons obscured by an icon on top. The transparency does not allow you to see through to the actual desktop background. Disabling this effect causes Windows to display the desktop more quickly. This setting is an important one in that it controls the new look of Windows XP. If you disable it, your desktop will look like previous versions of Windows.
