When i hover/cursor on-top of an item typically it pops up the item details (item help); however, as of this morning it no longer works in inventory, in armory chest, in vendors.

I have confirmed it is enabled in my HUD (never changed it), it is on-screen and opaque (non-transparent). How do I enable the functionality? Is there somewhere to do this apart from the "HUD Layout"? I could find nothing in Character config. nor in System config. settings.

Please help.
