Button reacts six times upon one click (undesired)

Hello! I recently upgraded unity to 1.2f1 and reimported my project. Then I discovered t$$anonymous$$s issue: the buttons respond 6 times with only one click. T$$anonymous$$s is not wanted and causes many issues. The button responds exactly 6 times with every click every time. It sends a message to a gameobject that reloads the scene. T$$anonymous$$s gameobject has a DontDestroyOnLoad but would destroy itself if receives the message from the button. So with every click it loads the scene six times. I tried commenting out the reload scene function, then created a test object. Still, with one click, the button sends messages to the test object and provoked a function 6 times. I know t$$anonymous$$s because it debugs a log I put in that function 6 times. If anyone knows the solution for t$$anonymous$$s issue, please tell me. I greatly appreciate your help. Thank you.
