Hi there,
I am making an add-in for arcmap 10 in Java. I followed the guide for creating a new button on this link:

my problem is: the first time i insert a button on the toolbar I have no problem. BUT if i close and reopen the arcmap the button gets put on the toolbar many many times. Does anybody know why this happens??
Thank you for listening. i hope this problem can get resolved. 
Please help me.
