InteractiveCloth & ClothRenderer pauseWhenNotVisible issue

If 'ClothRenderer.pauseWhenNotVisible' is applied, toggling the active state of the parent object causes the cloth simulation to pause and not recover it's simulation (i.e the cloth becomes static) on the second round of disable -> enable.

If 'ClothRenderer.pauseWhenNotVisible' is false all is working as intended (as you'd expect but having a cloth sim running in the background is not good).

Setup factoids:

• Running on Unity 4.x Beta (problem was still there in Unity 3.x and the .activeSelf/InHierarchy are behaving as expected)

Failed solution attempts to date:

• Manually calling SendMessage("OnBecameVisible") to the object with the cloth components; Unity asserts with 'no message receiver' warning; this led me on to:

• Adding a script to the object so to ensure the object is receiving OnBecameVisible/Invisible calls and also verify all .active flags are set as expected: when made visible the obejct receives 2 of these calls from Unity and yet nothing

• Calling AddForceAtPosition on activate to jostle cloth into action; no effect

• Toggling InteractiveCloth.enabled in an attempt to kickstart the simulation; nada

Any further help or suggestions would be greatly appreciated!
