I am running Mountain Lion OSX 10.8.2 on an Imac. When I click to open Zimbra, a dialog box opens and closes so fast I can't see what it says and then the Zimbra icon shows on my dock. If I click the icon on the dock, it immediately opens to full screen as it should. I don't know what to check or change to make it open full screen to start with.

Any and all help is most appreciated...

Thanks
