I hope I have placed this post in the correct area of the forum.
Yesterday I thought I would tidy up the icons on my desktop by adding some to appropriate areas of the dock by dragging and dropping. I also took the opportunity to rename and rearrange older icons already in the dock. All was fine until I switched on the PC this morning to discover all the new items had gone from the dock. The older items that I had rearranged and renamed had also reverted back to their previous settings.
Have I missed out something vital or is there just a bug in the dock feature?
