Just want to bring this to your attention, not sure if it was ment to do so, but there was a click function in 1.3.3 that is missing from 1.3.4b.

1.3.3 seem to treat every wow instance as it's on top, I can move my mouse over and do my regular operation, this click function is missing, 1.3.4b I'll have to click on each instance first before I can do anything.

For example, turn in quest, in 1.3.3 I can right click and turn in quests, in 1.3.4 I'll have to double click to turn in quest, it essentially is a double click, but when moving through many alts, it can slow down a bit.

Not sure if the software was meant to do so.
