Quadra 840AV: Icon Relocation Fixed In Display Enabler

All desktop icons on a Quadra 840AV or 660AV shift to the right side of the screen at resolutions higher than 640x480. This happens with both Display Enabler 1.0 or 1.1 and either Multiple Scan 17 or 20 Displays.

Leaving a Finder window open before restarting or shutting down, will usually rearrange the icons in that window, instead of on the desktop. Is there a way to correct this problem?
Installing Display Software 1.2 or later corrects this problem. The software is available from the Apple Software Updates Web site at http://www.apple.com/swupdates/ .
