In case of Show Hide behaivors the action sets order doesn't matter, unless those are chained. In case of a chained action sets the "son" action set will occured after the "parent" action set.

I will think of an example and I will attached it to this reply as soon as I build it.

To add an element as a target you need to press the green plus sign to the right as shown in the image bellow:

I've tested this and it worked great. I've attached a sample of the scale behavior with same numbers as you tried. Let me know if this helped:

152 - Scale Behavior.zip

Were you able to update the next time you opened IB3? Or this error persist?

Just import the background as a normal element and then add a Drag-DrawFree behavior with Target (self).

You don't have to copy paste the action sets everytime, if you want to add more targets.You can do that simply by using the green plus sign to the right as shown in the image bellow:

What do you mean by copying it back to the same element?

When you can't see the intersections that you have created try to go into another page and then go back to the page you are working on. You should be able to see them then.

The processing speed depends on how many elements you have on your current working page and also on how your CPU is used.So if you have opened for example another 5 processes and you work on a page with let's say 40 elements, InteractBuilder will act slower.

Ok I manage to see this bug. So when you apply a template it will add the Copy tag next to the elements from the template. This is definetly a bug and we are working to fix it.
