XPU 4.X can be preinstalled on a system that has no support for a mouse or HID devices, however, this requires the user to insert the Windows system disk during the installation.

#### Acoustic Pulse Recognition (APR)

- Support for Acoustic Pulse Recognition
- New way of sensing touch by recognizing the sound created when the glass is touched at a given position.

Bug fixes in this version:

- Intermittent loss of touch and activation of and the "Disable Touch" feature in the Elo control panel
- Windows Server 2003 would hang during the boot process because the Elo Service Application failed to load.
- The EloGetTouch API function would not return touch data within a "no touch" rectangle. It now returns touch data irrespective of the touch rectangles defined on the screen.
- The EloGetTouch API function reports incorrect coordinates in 'Drag' mode.
- The installation application sometimes causes a system message pop-up dialog box that prompts users to select the file location when installing a Serial only package.
- The tool tray menu sometimes hides the taskbar. It now appears above the taskbar and is larger to permit easier option selection.
- The touch mode sometimes changes to Mouse emulation mode after the video alignment application exited with a timeout.
