Why is any scene with an NGUI UI marked as dirty when the scene is open?

Why is any scene with an NGUI UI marked as dirty when the scene is open?  I have different NGUI Roots, panels, widgets, etc. in different scenes.  In every scene, the scene is marked as dirty when I open it.  This is pretty frustrating because it makes it difficult to remember when I have actually edited a scene and need to save it (and commit the change to svn).  Is this just an issue with NGUI or have I done something wrong with my implementation?

Thanks.

That is one question I have not been able to figure out an answer to myself. Even removing all instances of SetDirty calls and adding extensive Debug.Logs, I saw no clear indication of what was causing the scene to get marked as edited.

Even creating a scene, adding a UIPanel with an invisible widget under it, then disabling both components, saving the scene, deselecting the object, and alt-tabbing twice marks the scene as edited.

Edit: On second thought... it might be the OnApplicationPause function in UIWidget that's causing it. Editor calls it. Remove it.

Sorry for the lack of response.  I hadn't marked the thread to notify me so I didn't realize you responded.  Thanks, btw.  The changes in 3.5.2 have helped quite a bit.
