Many folks are reporting that the bank frame is not updating when they open it. Only after the close it again are the changes they made actually viewable.

Pretty sure this was fixed :P

This issue only occurs when right clicking an item to move it to and from the bank tab. If you left click to stick the item to your cursor and then click it in a bag slot, the bank slot updates appropriately.

[edit] Actually, i was wrong. The issue occurs all the time. The only time it does not is if I withdraw a bank item and then place it back on the same slot.
