It's more than likely an issue with an application not shutting down properly possibly causing Windows to revert to a previously used arrangement. If you open Event Viewer, does it show any errors concerning application shutdown?
Also, I find that 'sometimes' icons will move about if something has caused your resolution to change, even for a split second. Are you running any apps that might not be 100% compatible with the features your using

Hope this helps
Right click on your desktop and take auto arrange off etc.. It should save on exit if you shut down properly.
