layers and D&D

I have some feedback screens inside a display set and I have a drag and drop activity that just lives on the main page without being inside any display set.
The DD positions a small graphic in a spot that ends up being right on top of the final success feedback and while I can move the feedback display, I was wondering why it shows up on TOP of the display set, even though in the cast order it's nowhere near the top layer. Is there some kind of hierarchy of layering that overrides and forces DD objects to top?

Hi Tahiya,
Yes, it is a bit odd. Basically, the drag elements (and their feedback) float to the top when you pick them up. They'll float above anything that you put in their way, whether it is in a Display or on the stage level. I believe this is so that when you drag something, it doesn't accidentally get pulled under something else (like other drag items or the drop zone).

So what you'll have to do (if you want to fix this - if you're okay with just moving your final feedback you don't have to) is put the drag and drop inside a Display Set. If they're in a Display Set, the drag objects and the feedback can only float as high as the Display, and you can layer things on top of it. This comes up whenever you want to put a mask on top of the drag items (for example they've dropped everything and you want to keep them from changing their answer as you show them final feedback). This concept is illustrated at the beginning of this particular video - (gosh I sound like a robot in that video).

oh, and I am hoping someday to become at least 50% machine so sounding like a robot is kind of cool in my book. :>
