TreasureIsland, 'bumping' a post is usually sufficient. creating a second, identical post only causes confusion...
That having been said, I wish I could help you. I have Fences Pro. I think that if you take a snap shot using the option in Fences (after arranging your icons) you'll be able to return more quickly to your desired baseline.
There also should be a way to "save settings"... which I just don't remember for the free Fences.
The snapshots are stored under:
Vista/7: C:\Users\USER_NAME\AppData\Roaming\Stardock\Fences\Backups
Hope this helps...
