Since the patch there is a significant new delay when alt-tabbing between EQ instances. After releasing the keys I get a 0.5 to 0.75 second black screen before I get switched to the character I am changing to. FWIW I am running both chars in full screen mode, and have never had this issue before the patch. Ideally, this gets fixed. If this is something we are going to have to live with, please advise so we can adjust our expectations. It really adds a painful wrinkle to boxing without third party software.
