On my macs (10.8.3), the login window keeps popping up (with the username and password completed) taking desktop focus and requiring me to just hit "login". This is annoying.
It appears that some periodic ping back to the opendrive servers is failing and prompting the popup. Obviously the data and login are correct as it all is okay again after clicking the login button. Can something be done to at least have the failed access retried a few times before the stupid popup is displayed again? It is very annoying.
