Thank you for the update. It appears that there is definitely still a glitch. What is the desired effect you are looking for and what are you attempting to implement? I think that knowing a bit more about your application may help us to figure out the best way to go about displaying the data.
Please see the forum below which discusses overlapping front panel objects and using tab control

Lastly, I would recommend creating a new forum post for your particular problem, as this one was created over two years ago and may not be getting as much traffic.
Thanks!
