RealCADD and iPocket Draw

I just installed the latest version, and I've run into a problem. I start by drawing a rectangle, select it, and convert to lines. No problem.

However, when I try to tap on a line to select it for (for example) a Duplicate and Move, the line moves from its position. I don't remember this happening before. If I'm really careful with the tap, it will just select, but a "normal" tap draws the line away from where it belongs.

I really don't remember this sensitivity in the previous versions.

Bonjour Mike,

Strange, because I don't have made change on this part of iPocket Draw.
And I can't reproduce this.
Do you have this problem with all drawings?

Thanks.

Eric,
It seems to be in any new document.

More information: I am now using an iPad Air 2. I tried installing the app on my wife's Air 1 (my old tablet) and it worked correctly.

Bonjour Mike,

Damned, Noel is gone... Now I have to buy a new iPad Air 2 to test iPocket Draw on it.

You know you wanted one, anyway!
