Semi-necrothread..
So what is the fix for this? It was never answered here. I want my docks to be in the background. When I run something maximized it stays in the foreground and just mucks things up.
The Accessibility option will not let me select anything other than Tabs on top.
AhHH.. figured it out. Must be a bug too.
I switched the position setting to Floating. Once I did that it seemed to unlock the Accessibility setting, regardless of what position I set it to.
