Instance skipping with next window

Someone please help,

I use a stacked layout with 6 instances up at once. When I use my next window key, it will skip instances. Sometimes 1, sometimes all and everything in-between. I have seen a few topis with this same problem, but none of them had any confirmed solutions.

I have tried fresh installations of both the Innerspace/Boxersuite and Everquest. Used default settings and wizards. Nothing works.

I want to play so bad, any help would be appreciated.
