problem with TeamViewer on Mac Air

[ilantal]

I'm not sure this is the best place to ask, but here goes. I'm using TeamViewer, which is a very nice program. The problem is that it comes up on log in when I don't want to use it. If I happen to forget, this could be a security problem.
The option in TeamViewer to come up on login is NOT checked, so I don't know where it gets the idea to come up on its own.
Any suggestions?
Thanks,
Ilan

Later on we found another checkbox in TeamViewer for starting team viewer on startup. This was checked and unchecking it fixed the problem. Thanks....
