SourceTree constantly asking for login credentials

Question

I have SourceTree 1.9.6.1 running on Windows 7 Enterprise SP1. A dialog window is constantly poping up stating "Login required for : ..." I have my remote set up with ssh. I have searched the net and tried every thing to resolve the issue, but the dialog continues to pop up and seems to not recognize anything I enter.  Can anyone tell me why this is happening and how to stop it?

For now, the only work around is to turn of checking the remote for updates, under Tools | Options | General | Repo Settings.
