Multi-Touch doesn't work

[yuefeng]

I am sure to enabled "use multi-touch" on the tk2dUIManager, but when I hold button A, it will automatically release when I press button B.

And I noticed that the "UiCamera" on tk2dUIManager will become "None" when I play the game, how to solve that?

Big Thanks !

Do you have more than one of the UI managers in your scene?
