Am I stupid?! No tooltip when I hover over link in chat

[bdkdave]

Granted I've been away from the game for a while, so maybe I'm missing something, but in the past, I've been able to hover over links in the chat window, and have their tooltip pop up. Now I have to click to see the info, and that's just plain annoying!

This is driving me nuts. To the point that I've performed a "fresh" install of WoW, with the ONLY addon installed being nUI. No dice.

So I installed Prat, which I used with my prior UI loadout. (Sorry - it was before I discovered nUI Still no dice.

Searched for other addons - LinkHover, Prat - LinkHover, all with no dice.

Is nUI blocking the ability somehow?

thanks for a spectacular product!
