On the transactions list, 6/21/06 displays, but 6/22/06 turns into 6/2..., probably because of width issues; this may be very dependent on UI scaling questions.
I saw this same problem. I modified line 125 of AuctionFrameTransaction.lua to set the width of the date column to 90, rather than 80, and the problem was corrected. You will have to decide if "90" is right, or was just a going starting point. Also, do you have any thougths/plans about allowing users to change the formatting of this columns data? "%x" yields a two-digit year for me, and I just find that kinda annoying... Thanks.
