Sorry, I've read it as "repo"
Here's how to reproduce the bug:
1. create a new project
2. import 2d toolkit 2.5.0
3. delete main camera
4. add 2dtoolkit camera
5. Set the camera to:
Native Resolution: 640 x 1136
Preview Resolution: 640 x 1136
Pixel Per Meter: 1
6. Open the sprite collection: UIDemoSpriteCollection
7. Go to settings, change size to Pixel Per Meter: 1
8. Click Commit.
9. Now drag the Window.prefab from (tk2dUI_demo/ControlPrefabs/Layout) to the scene.
10. Highlight the "Background" gameobject that is inside the "Window" gameobject.
11. Click (1:1).
12. Now highlight "Window", and you won't see the handles because they are very tiny.
13. You have to zooooooooooom, then you'll see a small rectangle, with handles.
