Game Mechanics: Mouse over Preview

[fohkure]

My mouse over preview of spells/items has completely stopped working. I rebooted and still nothing. I have to actually long click an item to see what it is in my bag. In other words, I can't tell the difference between a stave of shielding and a burnished wooden stave unless i actually open the items window. The same goes for spells, i can't tell the difference between Spirit of Wolf and Celerity without casting them.
