New question, is it possible to lock or fix desktop icons inside a Fence
It's still frustrating to manually return things to their original setting, original being where I'd like them to be placed.
But this sounds different that than the prior question, meaning, you want Fences - not icons - to retain their position after a resolution change. As was pointed out, and as you seem to have found, snapshots would help with that. Also, this option:
If your actual question is
'I don't want to have to go to snapshots to help restore my desktop - I would perhaps want to script it with a batch file (or something)'
No, but it is being considered.
