Hello,
i run Unity 5.1.1f1
i recently tired to update my 3.8.2 NGUI Version to the latest 3.9.1 and also import HUDTExt 1.13 to an existing project.
I did as i should, new scene, delete NGUI Folder, import NGUI. No errors so far, but when i start the game i get weird mouse behavior. When i scroll the screen and have the cursor offset from the middle of the screen, it flickers and tend to jump to the middle while scrolling. This happens exactly when i do the upgrade. With the old version it's fine.
Also when i import HUDText (after having NGUI imported) i get the following compiler error:
Assets/NGUI/Examples/Scripts/Other/PlayIdleAnimations.cs(12,14): error CS0101: The namespace `global::' already contains a definition for `PlayIdleAnimations'
This happens, if i import HUDText to NGUI 3.8.2 or 3.9.1
