There appears to be a alignment problem that only appears to occur when clicking a linked item from the chat box (i.e. trade channel). The problem seems to only occur when the item description window is past a certain size. In that case, the tool tip will either not align properly (its short on the left hand side), or it will after a slight delay. The behavior appears to be inconsistent.
One thing I want to add to this is that the problem only occurs if the Auctioneer embed feature is turned off.
