Take an object that you own and have full perms on into inventory.
Right click and select 'properties'.
Change the name of the item, and close the dialog.
Displayed name in inventory does not change, even if you close and re-open the folder.
Check the Properties - it's correct in this dialog.
Close the dialog again.
Displayed name is still wrong.
Right click and select 'Rename'.
Before you can type anything, the new name shows up, and remans OK after that.
