Not sure what caused this. I've had no issue up to this point with alchemy tables. Today, for the first time, I tried to access an enchanters table. I have two weapons in my inventory that have enchants (Frost, Soul Trap) but when I click on the table, my character drops into an attack position but the table dialogue option won't open up.

I've tried closing the game and restarting the game at that save point. No luck. I then went to the adjacent alchemy table (this is in the wizards office in Whiterun). The alchemy table now does the same thing.
