AppleVision 1710AV: Icons Rearranging

I have a Power Macintosh 7100/66AV, running System 7.5.1, and an AppleVision 1710AV display. On startup or restart the desktop will automatically rearrange all of the icons on the desktop in alphabetical order on the right side of the screen, as if I had chosen the "Clean up all" command from the Special menu.

I have found that leaving a Finder window open in icon view before restarting or shutting down, will alphabetically rearrange the icons in that window, instead of on the desktop. Is there a way to correct this problem?
Workarounds

System 7.5 System 7.5 or Earlier System Software
* Note: If you have any external volumes (hard drive, server, or other) that automatically mounts at startup, you will need to leave an empty open folder on the last mounting volume. If other volumes mount at startup after the empty window opens, the window will move to the background--and will not prevent reorganization.
