I did a postponed windows update yesterday, and since then I have been having the '1 sec desktop flash, or alt-tab' every loading screen. I've played GW2 for well over a month, and have never had this issue!Have not tried the focus assist thing, but will later today.Anyway, any update on this matter? I see a GM posted about a solution being under way, but still nothing a month later? Best regards
