I think I may not understand fully how memcpy works.

So I have a struct which has several panels in it which You can see on screen. I loaded one up and wanted to simply copy that struct to a new one. I used memcpy the way it shows in the manual but I still only have one visible panel on screen. Which now behaves the way I set the second one two. I made several of these, 70, and still one panel and all behave the way one of them should. i can tell all of the functions are working but they are not moving the panel at 70 times the rate of speed as I would expect.

Any helpful advice that my point me in the right direction?
