I just registered to get help with a very similar problem. I'm on the first day of my 30 day trial and things are not going well. I already had my desktop reasonably well organized and started the trial after reading that my desktop would be restored intact if I decided to uninstall Fences.
I selected the startup option for Fences to arrange all...and didn't like what I saw so looked for an undo feature...couldn't find it. Eventually, I uninstalled/rebooted and, horror, all my 150+ icons were arranged at the left side of my desktop in a complete jumble...not in the arrangement I started with and had evolved over several years. A second reboot didn't help.
Luckily for me, I have a utility called DesktopOK that saves/restores desktop arrangements...for some reason it would not work until, after several attempts, it did restore my desktop icons. OK, back to square 1.
Attempt 2. Reinstalled Fences. Immediately, my icons were sent to the left side of my desktop. Attempting to restore using DesktopOK with Fences running resulted in a momentary restoration followed by all icons back to left side juumble. So, I uninstalled rebooted for a second time and, again, DesktopOK did eventually restore my icon arrangement after 2-3 attempts.
What I wanted/expected from Fences was to initially leave my desktop untouched and allow me to set up desktop fences for selected icons and leave the rest alone. Then I could migrate stuff into fences over a time period. On my first install I did see a manual 'experienced users' option which I probably should have selected instead of the 'arrange all' option. On subsequent re-installs I'm not seeing it, just an immediate jumbling up of my icons to the left side. Any way I can get back to a 'clean install' situation?
If I can get some answers here I may try again and proceed with my 30 day trial. Otherwise....forget it.
