Ah, it seems it was a configuration problem. Copying your config fixed it!
One small issue though: it seems there is a problem with the offset for the items in the equipment slot list. The last item wont show the item in the slot, and scrolling down the window always cuts off the currently selected item. I think it is an issue with the "Equipped Items" title at the top of the item list, as the missing bit of space is always about the same as the height of that title. That, or it is just not scrolling enough to fit the full item slot name and the item into frame, just the title.
