Android, mouse and touch events on UIPopupList

[vvvua]

Popup list works only with swipe when mouse and touch controls on camera are enabled.
It seems that events are received in pairs. So one event opens the list and another closes one in the one same frame. Mouse is enabled with this script attached to the camera:

1. gameObject.GetComponent<UICamera>().useMouse=true;
2.  

Is it possible to ignore multiple events in one frame?
Or maybe I'm wrong in my assumption?
Thanks.

Enabling both mouse and touch events on android is a bad idea because Unity sends mouse events for touch events as well, which results in duplicates. NGUI disables them for a reason.
