So i just installed OS Lion on my late 2009 Macbook Pro and im getting something strange happening when i start it up. I've installed some of my usual programs like skype, smcfancontrol, Cinch, MBox Mail, Steam, etc.. But whenever i log off and back in or restart or shutdown and restart my machine i get this same folder opening up every time. i know its nothing to do with the "reopen Windows When Logging Back In" tick box because i've closed this folder window down as soon as its appearing. I would love to know what this could be and if it can be sorted without me having to do a fresh install again as this is already my 3rd fresh install today. Thank you.
