earlier i saw this: http://i.imgur.com/9E5pq.png …after rearranging the blogspot-tab(moving it to a different spot in the group, and back) the tab is now displayed beneath the opened stack. http://i.imgur.com/JC8VO.png z-index issue?

ehm. well, as i have mentioned, i was able to _fix_ the issue by simply rearranging the tabs. imho making sure that the stack-overlay has the highest z-index would fix any similar rendering issues.
