I'm still having trouble with the Page Menu in Ata 3.4.9 on WP 3.0.1. The latest problem is that the drop-downs in sub-pages are not moving out to the right. Rather, they're coming straight down and covering pages.
Oddly, it was working okay a few days ago.
I've now deactivated all plugins... and the problems persists. You can see it at http://paulskolnick.com.
Not sure if I'm using WP built-in menu system or Ata menu system... because neither seems to have a spot to deactivate it.
