You could actually rename an item? I wish I know how to do that, because I haven't figure it out yet.
I experience the same thing for being stuck at the enchanter table between 10-30 second, but I suspect that you can get stuck forever if you don't try to move your mouse.
When you say, "you wish you knew how" you don't mean the fact that need to press 'F' after having selected all three aspects of the enchantment do you? I don't mean to insult you if that's not what you meant.
If that
is what you meant, you can only rename once you've chosen the item, the enchantment, and the soul gem to use.
Do you not have the option to rename anything or does if give you the option but the 'F' key does not work?
They do have short character limits for renaming things I noticed, other than that it's working fine for me.
